roadster wheelbase

Adger Smith · 08-15-2011, 11:45 AM

Rick,
If wheelbase was the problem then a lot of the Gen 3 Camaro's would be in trouble with their 101" wheeldase. Vinney's Comp roadster I had made quite a few passes @ 145. I think the type rear tire made more difference in it's handling than anything. Those hi-growth thin sidewall tires are a handfull after the finishline. They had to come down and settle a little before using the brakes and chute. With the type tire used in S/G racing I see no problems.

You're right about the tires ,Adger.
I tried a set of soft sidewall tires when I first built my roadster to try and get some more MPH, and you could not drive the finishline with those tires!
I used to go 165 in my Willys when I cut it loose ,on a 100" wheelbase.
You knew you where going fast then!!

Tom, as I stated in my original post I am trying to get in a car that I feel more competitive in multiple classes . With that in mind, what changes do you make when switching from bracket racing to S/G ?

I keep the suspension my car in Heads up mode to bracket race,leave off my top bulb and hit the throttle on the second amber.
I shift on time ,early to keep the wheelstand down.

I own a Spitzer Roadster with 112" WB that I run in S/G. I shift on time, .05 and keep the suspension the same from .90 racing and bracket. I run a M/T stiff sidewall and have great consistancy at 155-160 mph.
