4 cyl vs GT suspension

K member is different (V8 has wider control arm mounts)
rotors are different (V8 rotors are bigger/better)
front spindles are different
struts are different (V8 mounting point is narrower)
sway bar (front) is different (bigger than 4 cyl)
sway bar bushings are different
calipers are different (V8 calipers are better)
brake lines are different (not a huge issue but they are different)
rear sway bar is nonexistant on 4 cyl cars
no quad shocks on 4 cyl cars
rack is different (V8 rack is quicker ratio than 4 cyl)
and a ton of other stuff is different too.

However....changing from 4 cyl to V8 suspension is not hard.

Swap the brakes, calipers, rotors, struts, K member, spindles, sway bar and rack from a GT or V8 LX onto your 4 cyl car. It all bolts right on. The K-member is not really required but to have it correct, you'd want it. Mine is the original 4 cyl K member but with all the GT suspension stuff & brakes, rack, and better bushings. 4 cyl cars are terriblly boring but with the GT/V8 suspension, they handle a LOT better! Also, because the control arm mounting points are narrower on the 4 cyl cars, if you don't change the rack, you'll definitely need to adjust the toe. Better to have complete alignment done. Mine drives GREAT other than the JUNK struts and shocks that ride like poo.

And the comment about the 4 cyl cars and V8 cars being the same, it's not ENTIRELY true. There's thousands of little differences, from wiring harnesses to clips, vacuum trees, suspension & brake stuff...all kinds of differences. For those of you swapping a 4 cyl to a V8, you're much better off finding a V8 car to start with and selling the 4 cyl car. Speaking from experience!

i need help im swaping the front suspension from a v8 car to my 4cyl, the only problem i have ran into is the shock mount at the top of the shock tower. it seems that i will have to grind down the hole where the shock goes throu to get it to aline right. is this normal?

I just put everything from an '88 Turbo Coupe on my 4cyl a couple of weeks ago. Should be the same stuff as a GT. I haven't set it on the ground yet or gotten it aligned, but it all fit together nicely. Doesn't sound normal to me.
