Jason, I really appreciate all of the information you have gathered and distributed during this build. I am really looking forward to your thoughts on the spring rates you have chosen once you get some seat time.
Thanks for the update Jason! Love following your build and website.
If I can throw my thinking cap on with you.
On the El Toro runs, it looks like you could be locking up the rear tires under braking? To me, it looks like that is really what's unsettling the car on turn in and keeping you so busy. In contrast, mid-corner to corner out, the car looks pretty manageable.
You're obviously a good driver, the car just looks really skittish right now but I'm sure you'll get it sorted soon enough.
Hi Steven,
I think you're absolutely right, that the rear brakes are locking up. Was up late on Wilwood's site last night looking for different calipers that would shift braking bias forward. Think I have a solution in mind.
In a different setting I might try a proportioning valve, but it's not legal in the class.
Cheaper, yes, but I don't feel that is as good a solution. Different pad compounds behave differently as temperatures rise and fall, which would also shift the bias around somewhat unpredictably. With a little less rear piston area, the bias should be consistently shifted forward.
An old ponycar's last problem is power - I'm sure with headers, exhaust, and a solidly (but legally) rebuilt motor, you'd have more than enough power. Most cars in the class are below 200whp - but they are also small, light, with great handling and braking. Power is not that important in autocross.
I still run with a SBC307 and definitely the last thing i worry about is the power , getting around corners and stopping are a bigger concern . You just have to go out and give it a try and learn from the experience and for a while get used to being slower than 1600 hatchbacks . Pete
