I was interested in order from them but started to hesitate.

Anyway, I want to pick up these Moroso control arms...
http://www.eraceparts.com/item...28384

any of you know where else I can pick them up from? I am having difficulty finding these.

THX

 

NOOOOOO! Don't doo Eeeet!

They will break.

Too wimpy - drag racing only (that's what the word "racing" means you know).

Hmmmmm- somebody needs to make some Roadrace worthy tubolare LCA's and uprights for the DC2...take maybe 12 lbs unsprung off each front corner...

Scott, who thinks it'd be nice too if somebody made some proper stub axles so we could run real racing cv's and axles...Big Hollow Axles...MORE LIGHTNESS!

 

that stuff is no good Scott? I'm going to have tubular control arms in there no matter what it takes and figured $400 for the pair ain't so bad compared to what a local fab guy will charge me. I suppose I can do all the work and make all the jigs and just have some friends weld up the arms for me.

I was also just thinking about modifying the Moroso ones...

 

drag racers dont even use those things

 

lol, I think they're discontinued too.

speaking of tubular control arms, do any of you guys remember that company that made tubular rear trailing arms that relocated the spindle? I thought it was kinda lame about 8 years ago, but now that I know better, they were doing it right. maintain stock suspension geometry while lowering ride height! I doubt anyone remembers...

 

I'm just looking at the tube OD and the damper fork mounting boss (and the way the design preserves the original cantilevering wrt the path to the inboard rear pickup) and thinking that that's not enough section no matter how thick the wall.

There's no practical reason for not running a tube in a straight line from the LBJ to the rear inboard joint. We don't turn our wheels enought to need all that clearance.

Scott, who just can't see those Moroso LCA's surviving too many laps of slamming 1200 lbs of spring rate into the curbs...

 

That was Ryane. I've still got one of their slicks and some pics of both the upright and the TA. I'll dig them out and post them. They came up in a thread not that long ago.

Scott, who daydreams about saving weight...about nothing in other words...

 

good input Scott, I'll have to come up with a good design around the pivot point of the shock fork

I knew you'd come thru!

 

Man you are saving so much weight your car is gonna buckle and break to pieces on the first turn.

 

The goal is to build the lightest car possible with all the minimum requirements for road racing without meeting a minimum weight for a specific class. I want to feel 7 lbs per HP

 

The RTR TSX's have LCA's fab'd from tube or sheet - it was hard to tell.

But they were typical in how they handled the cantilevered load - the cross section was largest at the fork mounting boss and tapered in both in and outboard directions.

Here's the best pic I got of the RTR:

and here's a glimpse of Tri-Points:


RTR's LCA's were one welded assembly, whereas Tri-Point's compression tube was attached to the main member with a clevis yoke.

Scott, who realizes that these are huge loads in the GFCP...or as I'm starting to call it the UOJSCP...

 

Man do I need to do some catching up with the world challenge cars. Great pix. This is going to be fun.


Interesting how RTR is using a rotor with more than 48 vanes...must inhibbit air flow for sure!

Am I also to assume the TSX's have removed the front anti-sway bar?

i would assume those vanes are only an inch or so deep and theres 1 or 2 more rows of vanes from the inside-out, dont you think? all for the sake of increased surface area.

Only sometimes. You want to hear evasions and dissembling? Just ask them about it.

Scott, who would kinda like to go to watch at Laguna...but isn't.

chances are those vanes are staggered like usual. If it isnt like the typical brembo rotors, well they better have some fans in the brake ducts like NASCAR

Interesting. Why bother with removing it all together when you can just disconnect the links?

Either way I am not surprised you found them without a front swaybar. When you adjust your roll centers, I imagined you would decrease your dependence on a sway bar....seems to be true.

 

They were running standoff's pressed into the LBJ boss, and I'd guess that they didn't mind that that would raise the front roll center.

I really think that Eric Broadley had it right: nobody wants to expose the depth of their ignorance. So just imagine if they think they know something.

Scott, who less and less thinks he knows anything...is this the path to enlightenment?

The more you know, the more you realize you don't know.

So if you are extremely bright then you need to learn relatively little to realize you don't know very much?

Scott, who still likes to learn...I just hate learning Nothing.

This will be my saying of the day at work. So true.

 

"Real knowledge is to know the extent of one's ignorance" - Confucius

 

I did have these in the works about 4 years ago, but the pick up points were in the same location. not a "drop spindle" trailing arm...


and this LCA was not my design. I almost died at Big Willow when they broke. Thank God I was using my TE37s that day instead of those 17" RO_JO Motego anchors. The inner 15" wheel lip saved my life.



This is revision -01:


It helps to have a fab guy that has some engineering understanding.

 

Where's the sway bar end up in that picture? endlink in front of the shock?

Thats an old ST bar that attaches to the shock mount. It didnt work when I swapped from non type R LCAs and shocks to type R LCAs and shocks. The sway bar just ended up twisting the LCA. Pretty lame, I ADDED understeer to the car. The Super Functions were definitely cool coilovers nonetheless.
