Okay after reading all these posts some are correct and some are completely wrong! Brett, Need to get rid of the 22yr old mindset of "just going in a straight line"!!
Not really sure of how many are out there today that are auto-Xing there TR's but I sure have! I'm here to tell everyone that these cars will surprise you and others on a auto X course! Just sit back a minute and think about it, Our TR's came factory with a 4-link suspension that does work quite well.
I Auto crossed my old Buick GN, Drifted my old GN with not much mods at all and kept up with some of the top competitors! Right now i'm building my current White T-Type for that very purpose. Corner Carver!!
Here are some of the Biggest issues with the TR that need to be adressed to be competitive:
1) These cars Push like PIGS in the turns so the larger the tire out front the better to elliminate that push.
2) Another thing is "Bracing" the more bracing the better to help eliminate "Flex". (Frame bracing, GNX braces, urathane body bushings)
3) "Brakes" Here people seem to go way over board when it's really not needed. Simply replace the front calipers with dual piston SSBC calipers (bolt on) and slotted rotors.
Out back change over to F-body disc brakes and that is good enough for autocrossing but if you were to roadrace they will heat up too fast/much and will need to go larger.
4) TIRES - Like Eric mentioned before, Tires are a HUGE part in making the TR handle MUCH better! I went from 15'' wheels to 17'' wheels on my old GN and it was a HUGE difference then I went to 18'' wheels and much wider on my current T-Type, MAJOR difference!! I will probubly have 265's on the front by next summer! :biggrin:
TR's handle great in the curves with little mods! Not just straight line cars!!
