- PFS cradle
- Aspec type brace
- Torsen swapped for T2 diff
- SuperPro Diff bushings
- RE toe links/trailing arms
- BFG Drag radials run them at ~30psi, they will spin/give some. May switch to ET streets, not sure.
- preload w/ handbrake or linelock

Diff will go first, next will be the axles, CV/inner, and after that the trans input shaft will go... plus toss in a couple motors in there somewhere... have fun.

I made 5 girdles, three for my cars and sold two. aicrotary2- Pm me and I can send you some pictures of what I made.

later

think its cheaper to get the cobra 8.8 instead ?

Guys on the v8 forum have been having great luck with the cobra swap. Its spendy, but its a pretty good bang for your buck in every other aspect. Great choices on gearing, and diffs, as well as having a higher strength threashold than the stocker. IIRC the parts are also cheaper to replace once you have swapped.

solid bushings and t2 diff.

I run JDM 86 T2 diff on 3:90 auto ring and pinion with stock axles.
at 568whp and 600+ft lbs i got 1.4x 60 fts on this setup on stock axles.
It is only a matter of time before i break an axle i am hoping to have the cash to put my 04 8.8 cobra IRS and axles in before my OEM axles break.
