Default Suspension Question...

Hey everyone....

My friend just got his Rsx Type S, and we drove on the highway and damn that car has nice grip, and handling, way better than my poor GS.

Anyway my future goals are to be a pruod R owner, probably next spring, what I am wondering is how does the R's suspension compare to the Type S's, since I was never in a R, Is the R's suspension and handling better or same?

Honestly your trying to compare apples and oranges. I Found that a lot of peoples have had a hard time making the Type S handle. I'm not just saying the R handles better because I have one however, it's a smaller car and a lot stiffer chassis, which is going to make it handle better

the Type R stock rocks the Type S

and even modded to the chin, double wishbone on the R will prevail

teh R is lighter, stiffer, more reinforced, lower center of gravity (this is huge!), mroe aerodynamic, so on and so forth

I wouldn't consider the Type R stiffer than a Type S in the chassis department. Having experienced both from a passenger perspective and the few that I've worked on, I'm going to give the stiffness award to the DC5.

Stock for stock, the DC2R will be better than a DC5S (LSD is rather nice, no?). Modified, I'm sure the DC5 will be faster but it probably won't "feel" the same. But who cares about feel if you're winning, right?

Are we talking about straightline or road course?

I'd take the modded ITR over the modded RSX-S on the road course.

I'm pretty sure the DC5 chassis is stiffer than the DC2, but since there are reinforcements made to the DC2-R, it might be a bit closer.

The DC2's double-wishbone setup is, no doubt, better. It is a smaller chassis; it does seem to be a better platform (except K-series &gt; B) for road-race.

In steady state cornering, as far as stability and G-load, the DC5 can be made to handle really quite well. It's a newer design than the DC2, and it has a nice, stiff body that allowed Honda to race the DC5 in all series without having to produce a special homologation version like they had to when the DC2 started falling apart on the track. The "Type R" is a version of the DC2 produced to compensate for various weaknesses of the DC2. The DC5's chassis does not have those weaknesses.

There are two reasons to have a McPherson car instead of a double wishbone car.

(1)The McPherson units are just cheaper to produce and simpler to install at the assembly point.

(2)Using a McPherson design on the front allows you to move a lot of metal around, creating a stiffer chassis overall and allowing you to create a relatively safer vehicle. The Honda EP3, for example, enjoys a very nice reputation for survivability in heavy crashes.

Where the DC2 will shine over the DC5 and EP3 is when you have them on a road course and start going over gaters and road vagaries, and having to switch back and forth while hitting these bumps.

The changes made to the 2005 DC5 make it a really very nice handling car, and one of the best thought-out McPherson designs...but it still <u>is</u> a McPherson design and so it suffers on the track when compared to the expensive double wishbones of the DC2 ITR.

I have experienced the McPherson weakness first hand because one of my industry acquaintances allowed me to drive a very well developed EP3 CTR on a road course. Having driven my own DC2 ITR on this same road course, I know that there is one section where the best way through is to bounce hard off of a gater on the right just before turning left.

This is not a big problem for the DC2.

You bounce off the gater, the car comes down, settles immediately, and then you turn left.

With the EP3 McPherson car, however, I'd bounce off the gater and I swear the car would come down in a different place every time, even though I've driven that course countless numbers of times and I'm really pretty damned sure I was hitting the gater in the same place every time.

Then the car would come down and you'd wait for it to settle...but it seemed to take just a split second longer than the DC2, and you'd kind of get the feeling the two front wheels were pointing in different directions, which would make me very uncertain of the car's attitude in that quick turn to the left.

I can't claim to be any kind of good driver, and I think that if a novice like me can notice a difference like that, then it's really very clear that the double wishbone design enjoys a definite advantage over the more modern McPherson designs in that particular kind of situation.

This doesn't mean you will always necessarily have the advantage with a DC2 car, because the DC5 or EP3 guy might just be a better driver, or he might have had more money to spend or more time to think about his chassis development.

Moreover, most purchasers of automobiles are not going to track the car, and if they do they certainly aren't going to track their cars as much as some of us do. So don't let us scare you away from the DC5. If you have track driving in mind as a serious hobby, however, then the DC2 will have an advantage.

If how the car feels unsettles the driver for .25 sec on a single turn, lap after lap, then he is going to lose the race to an equal driver with a more refined vehicle.

Actually, both. Of course, when I mention modded, it would include a LSD of some sort (probably from a DC5R).

Well, I meant "feel" as in subjective form. How the DC2 feels more direct than a DC5 from my limited seat time. But if the whole gater thing bothers ya that much, just drive around it instead of pounding on it.

In that case, instead of losing .25 seconds lap after lap, you will be losing .75 seconds lap after lap, because you are ignoring the fastest line when it's clear.

Maybe it's just the newbie track driver in me but I guess I just believe that if hopping over gaters is slowing me down, I'd try to figure out how to use the strengths of the DC5 and try to compensate. Perhaps just use the edge of the gater and use the additional grip that can be had on the DC5 (by riding on wider tires than a DC2 could) plus power out a tad earlier with the additional torque.

I'm still going to believe that given equal drivers, the DC5 will be faster than a DC2*.

* Of course, like I mentioned previously, I would have to throw in a LSD in the DC5 to make it a bit more fair.

You seem to have figured something out that Realtime and Spoon could not figure out.

I definitely don't agree.

Given two Equally prepped (i.e., equal money to both cars' development) cars at any level (stock, slightly modified, HC cars, World challenge) i'd say the DC2R always beats the DC5.

Seeing what King did to the WC DC5 in order to get it to their liking/be competitive... wow. You could build THREE WC DC2s with the time, money and resources spend on one DC5. I don't know that for sure, in fact I don't know much other than talking about the car at a few WC events and at Expo. But what custom work was done - was not necessary on the DC2s.

Odd. Looking at the qualifying results of Sebring in the 2003 season of WC (when both DC5s and DC2s ran the first race - no rewards weight yet), there is a 3 second difference between Kleinubing and Cunningham. I'm using the 2003 season because they're all on the same tire that year.

Also, in the Super Taikyu series overseas, on the same course (Sugo - too lazy to research any other track), the DC5s are also clearly faster than the DC2s when they ran there.

So am I missing something? Or are the numbers lying?

I dun think the numbers are lying....

the DC5R IS faster....but at the expense of more time in development and customized parts that Chris N mentioned.

Since "development" has ceased on the DC2-R for competition.... it will most certainly not be at the razor edge to be faster than the rest....

I'm no suspension engineer or even much of a technical car guy....but I believe the best thing would be to tack on double wishbones on the DC5R's chassis somehow....

But since that **** might be too hard to do.... just swap the K20 into the DC2 chassis and call it good.

To make it more of an (green) apple vs. (red) apple comparo....I'd like to see a DC5R vs. a DC2-R with K20 under the hood

Too bad the aftermarket isn't a strong enough force to convince Honda they FAWKED UP.... (IMHO) cuz race teams are using the TSX/Euro R and even Spoon is developing the Legend/RL now. Both of wish have the double weenieboners

But the DC2s has been around for so long. How much more development can you do on an older chassis? I think it was at the limit as is. And I'm not knocking the benefits of a double wishbone setup. I mean, look at the CL9s in WC compared to the DC5s.

I was just answering the OP on how I felt about the DC2 vs DC5.

I don't know if this is 100% spot-on correct - but the King/Mugen WC RSX has competely new suspension mounting points. The fab work/time/money on that must be astounding. AFAIK that equates to an entire NEW suspension geometry - or at least a lot of planning/equating/designing/fabbing/etc.

This was not done to the DC2 WC cars (i.e., RTR's for example).

Dollar for dollar comparison - the dc2 race cars ruled everyone and everything. The DC5 took some custom work to get to be competitive with the other challengers, more time, more money. And why did they run back to Double Wishbone with the TSX so fast? My guess is frustration with the DC5.

Yeah ....What he said..... ^^

But seriously.... even with the chassis as old as it is.... and again this is purely my opinion and speculation....

The DC2-R just needed more power, as I believe the older chassis design with the double wishbones can definitely handle it.

Again, red apple vs. green apple. K20 motor in DC2-R chassis vs. DC5R.

Well, for the track arguments. You may want to watch this (im hosting it):

http://www.neo-inc.com/ht/DC2RvsDC5R.mpg
http://www.neo-inc.com/ht/DC2RvsDC5Rpart2.mpg</TD></TR></TABLE>

What do you mean 'disrespects the Type R' ?

Does not respect the DC2-R? or DC5-R? and have they actually driven a Type R in similar situations as they drive their beloved Type S?

:Shrug: To each his own. IMO there is some very good accounts, like GK's, and some hard evidence that i'm sure is out there.. somewhere. problem is, where are the subject matter experts to share on this subject!!

For me seeing the fab work done on the DC5 to get it to competitive levels is enough for me to say the DC2 is a better/cheaper base for all us low/mid-budget enthusiasts/track day/honda challenge/honda cup/etc racers.

Best of both worlds = DC5 engine in DC2 chassis. As RagingAngel said, the DC2 is just lacking in the power department [B vs K].

But just don't rev those DC5 engines much past the stock rev limiter... or you might be caught in a heated discussion in the RR/Autox Forum about the two engines and a lot of ugly things get said...

By 2001 the DC2 ITR had permanent weight additions before any seasonal weight additions.

Moreover, in the season you mention, the money was already going to the DC5, not the DC2.

I'm a little puzzled why you're arguing about this. Am I missing something that's not evident from the facts and the conversation so far? Am I inadvertently insulting a DC5 closeted in your garage?

Probably. But it was just time to move on. The ITR was always expensive to produce, and the non-R versions were becoming too expensive. They were definitely dated.

Have you ever had to open and close the door of a jacked up ITR? Doesn't that worry you just a teeny bit when it's clear the door's not shutting properly?

That doesn't happen w/the EP3 and DC5. Very solid, and evidently safer than the DC2.

I have a feeling Realtime wouldn't even be campaigning the RSX if it wasn't for the strong push from Acura to do so.
