Bought my next round of mods for it this past weekend.
Independant rear setup from a 2003 Cobra. All stock with the exception of a BilletFlow diff. brace. Also has the BilletFlow rear bracket braces.
Magnaflow catback (same one I have on my car now, just the IRS specific version)
Maximum Motorsports rear coilover kit
I should be getting this installed sometime in the next month or so. I just need to get my Delrin bushing kit ordered.
