I want/need to get ahold of either a JIC Magic exhaust 505s stainless, or JIC Magic SF-1 or SA-1 coilover kit. could any of the vendors please get back to me on what the best price they can provide to me is?

Im also looking for information on the compatability of 2001 ls430 brakes with a 1990 ls400 (have 18" rims) (just need to know if all ill need is some fabrication for mounting, or if my braking system and lines
are powerful enough)

 

Try sending them a PM or email rather than posting here where they won't likely see it.

Click the link below to get more info on our vendors.

For what you're looking for I'd suggest Carson Toyota / Steve Ganz (SupraTRD on CL) or TM Engineering / Todd M (DoubleWhoosh on CL)
