How is the CR different that the AP2? I am shopping for an S2K and was wondering if the CR would be better for auto-x.

Sorry I have not done a lot of research. I am working long hours and the wife gets pis*ed when I spend a lot of time on the net. I was hoping to get some quick answers on the differences between CR and regular AP2. I have read the CR has a stiffer chassis. Does it have different shocks & springs or anything different in the suspension (bushings? sway bars, etc?)

thanks guys

PS. I 've been a member since '99 and still have my '99 GSR, but have not posted in a couple of years. After 11yrs it is time to sell the GSR and get a nicer car

 

It does have a set of different shock/springs and it is better in auto x because the turning radius is tighter.

Anyway here is a write up i found.
Handling
The handling of the CR is a significant improvement over the AP1. Body roll is reduced � frankly it�s nearly eliminated (amazing job Honda!) yet the CR doesn�t hop as much as the AP1 did around a turn with bumpy pavement. Pitch and dive? � almost zero!

Tires
The Bridgestone 070�s are a step up from the S02�s. Turn-in is sharp (although not as razor sharp as Yokohama�s A032�s or A048�s) and the sidewalls are nice and stiff providing good steering communication. I could actually live with these tires! Grip in wet conditions is also improved over the S02�s until you hit standing water. You�ll hydroplane as expected but no surprises that would spike the heart rate on the highway.

Engine
The engine pulls harder at all rpm�s and acceleration is improved in all gears thanks to lower ratios and a wider torque band. Redline in 1st gear comes at 37mph and redline in 2nd gear brings you to 58mph. Compare that to 42mph and 63mph respectively in the ole� AP1. VTEC cutover still occurs at 6,000rpm which means you have to rev 100rpm or so beyond the redline to stay in the power band otherwise you�ll drop out of power for less than � second during the upshift. The engine sounds good, runs smooth and has provided the same mpg as the engine in the AP1 Honestly though, I do miss the sound and the action that comes with 9,000rpm.

Noise, Vibration and Harshness
With the removal of the sound deadening material the CR comes with lots of low frequency NVH. The hardtop magnifies these frequencies which have replaced the wind noise that came with the soft top on the ole� AP1. I find that I�m a little more in tune with the engine and other noises than I was with the soft top on the AP1. I can hear the limited-slip differential better now.

Radio
I took the A/C and radio option. Radio is clear (no more paper cone speakers!) and powerful (no distortion at max volume). My complaint here is lack of MP3 playback capability.

 

If i were you i would grab a AP1/AP2 lighten it by gutting trunk swapping seats etc and still save a whole lot of dough instead of buying a CR.

 

Thanks for the info!

I am a little confused with your last post however.. I have been auto-xing for 9-10yrs and have even gotten FTD a couple of events (w/my GSR on Advanced Design double-adj. shocks/coilovers & Hoosiers) which is very hard to do with a ~185hp 2600lb FWD car.

How would making the car a little lighter, make it a better auto-x car when compared to the CR with stiffer factory chassis and different/better suspension? Only significant weight reduction and aftermarket suspension would equate to the CR's better handling I believe. I have learned from modifying the hek out of my GSR, that it is very costly and difficult to get a car to be equal or better than a factory-built stiffer chassis (Type-R) car.

I think I will look for a CR. I intend to auto-x it in A Stock so I can't do much weight reduction. I 'd rather leave the car stock (it retains its resale value too) and maybe change the shocks and get a cat-back exhaust for a little more HP, both of which are allowed mods in the Stock class (and not much else). However I think it would be hard to find better shocks than the CR factory ones unless they are really high end race shocks. I installed Koni Yellows on my brother's Type-R (stock springs and height, etc.) and the car handled better before when it had the stock shocks. No matter how we adjusted the Yellows, the car was about a second slower and was unbalanced. He is in the process of putting the stock shocks back on his R. The car was a lot more neutral and better balanced with them making it go through the slalom very fast. Maybe one of his Koni Yellows is not valved the same as the others.. don't know. Sometimes 1 turn of the **** on one Koni shock does not make it the same as the others. Koni Yellows are far from perfect unfortunately. I went through 3 sets on my GSR before I found a good set and only when I got them custom valved where they able to perform well and adjust equally (from left to right, etc.).
Anyway I will continue the search for a CR. So far the few that I have seen were on the West Coast. It seems like they are worth the a couple of $ grand more if they have less body roll, corner better and have virtually no pitch and dive.

 

If you can afford it get the CR.. I think Honda had the "Track" in mind when they decided to offer this model... That's from a stock point of view... But in my opinion an AP1/AP2 can handle like a CR with after market coilovers - the body roll factor. The CR comes hardtopped which is probably the best option for the S2k in my opinion 2. But that CR is nice right out the box!!!

 

Also one key difference between C/R and the regular AP2 is that the C/R uses the same steering ratio from the Ap1.

The aerodynamics of the spoiler and front lip reduce the overall coefficient of lift about 70%.

There is a shift light in the gauge cluster that comes on when you should shift in the most power of the powerband.

Weight- Normal s2k= about 2,864 lb
CR=2,765 lb (1,254 kg) w/o hardtop
=2,855 lb w/hardtop and ac/radio

The CR is a nice car, also it as a *sport* exhaust so may have a few more ponys on the dyno than a stock ap2. But I havent seen the dynos for that. Anyway, for all track it is awesome. If I can do good with my ap1 I probably get one. But as you can see with hardtop a savings of 9 pds I rather have my drop top ^_^

And you wont run into the problem I have with my AP1 OEM ECU. Hondata has a flash pro out for 06+. While I am lefts screwed right now thanks to RTA rules....

Here is an example of one at the track. Sexy.

For those that know the limitations of the SCCA stock rules, the CR is going to be faster than any other S2K. Here's an article that goes through a bit of the progression of the S2K up through the CR: http://www.roadandtrack.com/tests/ca...h-revving_hero.

 

that is cheating .

 

if ur gona run in the stock class which u say u are the cr will beat any other s2k hands down. In my local region the sides with cr's r mosters I was allways anywhere from2-3 secs off their pace and I was on tien flex with rcomps and minor bolt ons with a 00
