Looking to finally convert my rear to coilovers.

1. There is a popular thread on PFF about building you own but the links for parts no longer work.

2. Ground control's look to be to short and not a good option. Anyone use these with good results?

3. West Coast Fiero has an offering . Feedback anyone?

4. Hoping someone has a great option based upon first hand experience.

Thank you!

Dime

Well I am glad I asked fieroguru - thanks for the response! For some reason I was thinking your stuff was only for 88's.

I have a 3800 SC/4t65e HD - I believe (but it is a guess) the combo probably weight 100lbs +/- more than a 2.8 the stock Fiero 5 speed getrag.

For the past several years I have run with slightly cut rear springs (I think they are Fiero V6 springs) with the top hat flipped and my deck lid clearanced to fit. I have no complaints what so ever except they look.......STOCK. I would not want it much firmer or softer - pretty close to what I have....
Based upon what I have said, what spring rate would you suggest?

Rear coilovers are largely universal, so I offer them for all years of the Fiero. The only major difference is which set of holes in the strut hat I weld in the studs (84-87 have different bolt pattern than 88s, but the strut hats I use have both patterns).


I normally recommend springs in the 200 to 250 lb/in for those looking for close to stock level firmness.
I bias towards the lower end for stock engine/manual transmission applications and heavier engine/transmission swaps I bias toward the upper end.

Or build your own. See my web site for how I did mine.

Anything I might say is probably worth what you paid for it, so treat it accordingly!
