Which fiberglass bodykit is the best one for a 91 MR2? Has anyone installed one that actually fit the car without any mods to the kit? Thanks for your help.

Which is "best"? .... body kits are a personal choice, that answer is all up to you.

I have the aeroware kit on Jekyl and I had zero fitment issues.

i would think the original trd wide body kit... gl finding one though

Mcgoo69, I got your PM ... there are lots of photos of my kit on my Web site:
