Invader2 & Torque have widebody variants???
well you can fit any kit on any car if your shop is willing to do the fab work to make it fit. If you are wanting to do a widebody though, a cheap price shouldn't be your number one goal...it's going to be expensive, and you need to understand that. On top of whatever kit you go with and the work involved to make it fit, you will have to get an appropriate wheel setup that will fill the wider wheel wells. At this point you are in for probably $5000+ if you are doing it right.
Anyway I know that Qwhees?QEI?Scorcher has a widebody kit also; I think it's ugly as hell and I don't even know if they are still in business, but it's out there.
Personally I think you would be best off getting the ShineStreet with the fender flares...it's not really any cheaper and it still requires a lot of work because the parts aren't the best-fitting, but it looks much better than the others IMO.
