The 4th gen spindles won't work on these cars? Avoiding having to buy brackets and modifying the current spindles?

Totally different design. They actually use upper & lower control arms on this model.

Those wont fit a 15" wheel, I believe a c4 setup will though. Spindle mod and hub is stupid easy if you are able to do it yourself. You can also take it to a machine shop and have them do it. Shouldnt be more than an hour or two in labor

Re: ls1 front brake swap to 3rd gens

some aftermarket wheels will clear lsi rear brakes.i swapped in a 2000 rear end and my 15" wheels barely clear.i still haven't added the front lsi brakes so im not sure about that.
