Koni Yellows - APtuned.com seem to be the cheapest around at 800$ plus shipping (i emailed them for availability 55$ for shipping to me)
Koni spring sleeve kit for the front only (correct kit part# 30 0000 000 5 verified with Koni)- 43.76$ from Summit
Eibach 500lb 2.5x8 springs front- 131.94$ from Summit
Eibach 400lb 2.5x8 springs rear - 131.94$ from Summit
Megan Racing rear sleeves - 130$ (on back order for about 6weeks)
Megan Racing rear spring seat - 24$ (on back order for about 6weeks)

1316.64$ to my door

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.

I didn't have a great experience with truechoice, but my guess is you can do it cheaper piecing it together elsewhere...

Probably. Usually means it costs a lot when you don't list prices on your website lol

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.

Mike not sure if you remember me or not, but I'm driving an FRS now in STX and saw that you will also be at Wilmington in April. See you there!

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.
