88GT Road Race car build with a 3.4TDC (Page 9/18) Will AUG 29, 06:03 PM quote Originally posted by KurtAKX: What's the ballpark $$ for a set of to-spec spindles? Good question? Call them and ask? I haven't approached them yet as I haven't finished the design... and the exact nature of the design is going to impact the production cost considerably. darkhorizon SEP 03, 11:14 AM Heading to the famous Road America next weekend.... Bought a 7in digital dash and a bunch of pressure sensors to get ready for the stressful oil situations that RA will put me in. I am also going through the front suspension again, adding in the baer roll center adjusters again. Adding another degree of camber out back to help with the removed sway bar. WIll have some pics and updates in a few days. darkhorizon SEP 10, 11:10 PM Dash is in, pressure gauges working but havent put the final touches on the megasquirt driving the RPM/volts/temp yet. La fiera SEP 11, 11:13 AM That's pretty neat! Looking forward to see your videos!

Nothing yet, i should have clarified I didnt include the control arms in that, and i was just redoing the steering rack. Reports from road america are great, but also bad. Good news is the car ran flawlessly. Alternator repair over the last few weeks solved all of my misfire issues and throttle response issues. Also, racing my friends s2000 was not only very fun, but i was able to pull away in the corners while not losing any ground in the straights (figured it would be faster, but oh well). Bad news is that the high speed stability is absolutely crap, and I'm pretty sure it isn't aero related. I tried a few things but nothing really helped, the car has tons of grip but it "wanders" on the brakes and at speed with what feels like again a loose tie rod or something in the front end. I am going to see if the upper control arm butterflies are coming loose again. It tended to become very unsettled over bumps as well, which make me question the front suspension geometry as a whole package because its just not predictable and smooth enough for me to actually drive at the limit all the time. Many small slides and close calls when running at the limit, and one sketch slide at 115mph through a very dangerous turn called the kink.... not my car but a good angle that shows how scary this thing is.

The kink is sketchy in a lot of cars. My LS1 GTO did a 4 wheel slide at 120, My friends STI felt even less grounded. darkhorizon SEP 14, 04:26 PM quote Originally posted by FieroWannaBe: The kink is sketchy in a lot of cars. My LS1 GTO did a 4 wheel slide at 120, My friends STI felt even less grounded. I really feel like the areo is close to great on this car as it sits too, its just this darn front end "bump steer" that is giving me issues now. The rear is smooth and predictable with really nice slip angle and doesnt snap at all when loaded up.... just sucks to have a random number generator dictating what the front is doing. darkhorizon SEP 14, 04:30 PM Anyone have any great ideas to lock down the upper control arm adjustment better? The slotted bolt holes just arent giving me any good feelings no matter how hard I torque them down.... I dont think they failed this weekend but i feel like its a matter of time before they do. Will SEP 14, 05:04 PM How much caster are you running?
