Braking and balance
So, finally after a bunch of dicking around and bad weather, I've managed to take my Lotus "track" car out on a warn dry day. Affectionately know as the "Home Depot" special ( half the bits came from Home Depot and it's orange), I have stripped the car in a manner similar to the Sector 111 Spyder project. So no windshield, stripped interior, no glass, blah, blah. During the build, the majority of the weight savings came from in front of the engine, including, heater core, dash, glass, window mechanisms, wiper motor....basically anything that was excess weight is gone.
Now it became apparent during the build, that the lack of weight on the front might be an issue. This weekend proved it was, but to a lesser extent than I thought it would be. The problem now is understeer on throttle (auto cross) and front brake lock up. I'd love some input on some of the ideas I have to correct the problems.
I'm running the track pack Bilsteins (by choice at this point) primarily for the lower spring rates (along with 205/45/16 and 235/40/17 RE-71). Over the weekend I backe the adjustment to 4 clicks front, 6 clicks rear to induce some oversteer and help get some dive on the front (read extra weight. I am now contemplating disconnecting the sway bar to allow further grip and weight transfer. We ran 10 autocross runs this weekend, with temperatures ranging from the low 70's in the morning to high 80's in the afternoon. During that time, the front tires only got above 100 degrees in the last 2 runs, indicating to me insufficient grip. I've got about 1.2 negative camber in the front and 1/16 toe and about .75 negative rear and zero toe. I'm thinking I can dial out the oversteer with the shock and reduce the risk that way while picking up weight transition. Thoughts or alternatives?
Same issue. No weight, invasive abs and or lock up when it's disabled. Thinking running an aggressive rear pad, with a stock front to bias the braking that way, or a proportioning valve ( haven't figured the aspect of that in combination with abs yet). Again, thought and I put would be appreciated.
