Yeah, I can do that. I'm totally cool with trying out something new if it works better. But here's another idea...anyone wanna let me drive their RSR car??

I do want to update this thread in the future to let others know of my findings. I'll try to be as unbiased as possible.

"This is all theory and based on the popular belief that running larger rims and/or lowering the ride-height of any given car creates an undesirable effect of a lower control-arm that does not sit perfectly parallel to the road surface and by extension poor handling characteristics.."

This is not just a theory JJ. This IS what is happening on my car.

"Listen, 15-20 years ago - Shankle was it! That's what was available for these cars; that's what worked and it is still pretty good by today's standards however, technology has changed. Should we all still run carbs, just because that was what worked 40 years ago!?"

It's not just Shankle that sells uprated Torsion bars and springs...which is the onlything Shankle I have BTW. I just can't afford to buy even larger T-bars from OZ or Sweden, hence the use of Shankle. So it's not like I'm trying to target old technology (your carbuerretor example) but there's nothing that's convincing me that Ron is using "new" technology or whatever. His stuff IS NEW, and seems to work. That's reason enough to buy it, but not because it is NEW technology and mine is OLD technology. You could even say using just torsion bars and springs is the most elegant way to run a dual purpose transaxle car (I'm not adding coilovers onto an existing suspension system). I DO think that an all coilover front would be great though.

I want to point out that while I seem against Ron's coilover ontop of t-bar method, I actually know it has many merits, including a smooth ride before the springs kick in...I think that is quite cool actually.

Now, ofcourse Ron's cars are fast with RS kit. ANYTHING with stiff spring rates can be fast on ultra smooth roads. Anything. I'm even hearing my own points being given back to me in the above posts, infact (my VW bug example?). If you don't let the LCA's move, of course you're not going to run into geometry problems. And besides what looks like tremendously high build quality, what about Ron's stuff is new technology? Tacking on a coilover onto a torsion bar, and making some adjustable spring perches? I think what the appeal is, is for not a huge amount of money, you can pay for this man's R&D and get something that controls body roll, really, really, well. That still doesn't change the fact that the geometry is fuxored. If you run a car really stiff just to get around poor suspension geometry, you ARE losing potential. It's my belief that if Ron set up his Ring cars for better suspension geometry (Roll centers don't just create more or less roll after all, they also put force on the tires in sometime undesireable ways -- laterally versus putting load ontop of the tire) and used his kit, his cars would be even faster. Ron might not have changed his geometry on his race car, but the IMSA racers and the SZ engineers sure did. Why is that? And even with an RSR kit being around, why to people like Barry and others (on the gtv6.com/bb forum) go through the hassle of making their own control arms?

"Colin Chapman HIMSELF wrote that this is NOT necessarily true for ALL cars. It has also been proven in race-applications that if you can control the roll-center somewhat

You're saying the Lotus man said that the control arms don't have to be in proper angles on all cars, all of the time. Can you be more specific, so we can see if Colin meant his theory for cars like ours? Show me that what Colin said applies to us, and I think we can all take this statement with a bit more credibility.

The only RS kit I've gotten a ride in was Louis' 24V and and along time agon when Nizam drove me in Louis' Red Verde. I remember the Red Verde gripped like hell around some turns but my recent experience in the 24V tells me the suspension is WAY stiff. Too stiffy maybe for real roads? I believe Louis was mentioning the same thing when I was riding along with him. Maybe I was just riding in an example of Ron's kit that had too stiff fo springs, but in Louis' car the car felt over springed and underdamped (no offense please! I'm just stating my opinion of riding for half an hour in his car).

So I have to go now, but believe me, if I can't figure something out that is acceptable to me and Ron's kit is the best thing out there a year from now, I will be buying it. I mean, I've already have his sways, there's not much left


And how the devil do you make a proper quote?
