Alignment / Tire Advice for 20" Wheels
I've been running 20" Wald Streifens since I bought my '04 LS430 in 2007 and have burned though 4 tires and created a hairline crack (that was repaired) already. I use the Datasystem controller to lower it mildly (about 1" gap between tire and fender).
My car doesn't seem to be aligned properly although I've had it done twice already.
What's been your experience with 20"?
Specs:
2004 LS430
Wald Streifen Forged 8.5J 20ET38 Bridgestone Potenza RE960AS 255/35/20
Wald Streifen Forged 9.5J 20ET43 Bridgestone Potenza RE960AS 285/30/20
I'm about sick and tired and might just sell these and run the stock wheels if I can't find a solution.

Get the adjustable Megan arms for the back, you can set the alignment just right and stop eating up those expensive rear tires. I usually get 30k miles out of my 20" Toyo fronts. Although I do not have the Megan arms in the back, I had installed the shorter stock arms so that my camber was more upright, and since then my rears have worn fairly even.

hey doc, i had your issue a while back. there are two things i did to fix it. first was i had the 5mm shorter than stock rear OEM arms installed to reduce about a degree+ of negative camber and then i got it aligned at the daily drive height using the UL alignment figures which vary by .1 than the non UL figures if my memory is correct. these two things alone which were around $300 total saved me a bunch of rear tires.

1 per side. i don't have the link at the moment but they were about $100 a piece and are OEM directly from a lex parts seller like Seawell or Carson. I forget which I used, can someone post up a link. there are 3 choices. one is 5mm shorter than stock, one is the normal length and one is 5mm longer than stock. to reduce negative camber and save your tires from getting camber wear you want the 5mm shorter than stock arms.
