Try calling BC for the rear perches, I bet they are cheaper and in stock. Make sure the front sleeves are sold in a pair. You should look around on the interwebz for used springs. You can generally find pretty lightly used springs for way under new value. 75-90 is going rate for a used pair of Eibach/Hyperco.
ya the front sleeves are 21$ a piece. and I priced the springs as a set. 65$ per spring shipped . I tried calling BC but apparently they are still on holiday time and are not there. Ill try them back next week

There will probably be a lack of updates for a while. I apologize. Working a lot of hours during the week and trying to get the car back together for the first National in Georgia on the weekends. Have a hell of a list to get the car running again. It has not been been run since the second weekend of September.

Eventually I will finish this. I am also 95% sure I am going to take the car to F-prepared next year, so I will keep a running build/photo thread for that as well.
that is a 7 hour drive. how far do u guys travel for these events. also i know everyone keeps talking about the diff being the best upgrade. with them all fighting inside wheel spin. is these common with all stock diffs to do this. if so i have never had this problem from 245 street tires to 285 rs3 to my 295 a6. starting to wounder if it has a aftermarket diff in it.
dose anyone on here have adjustable caster. i have mine at 9 in the front. i was going of what others were telling me for setup. but i feel it is to high for auto x. i keep reading info like this "Increased caster effectively reduces the responsiveness, but also helps camber gain as mentioned. Good for street and high speed track, but poor for autocross. "
an congrats to the guys at nationals.
