Anyone know where i can get the stiffest rear springs for an FB? I dont want them to lower the car at all, I would actually prefer if it would be alittle bit higher in the back so I can maybe fit a taller slick under there. TIA

 

You can get 200 pound springs from Mazdatrix that fit the stock perches, IIRC.

 

I once remeber hearing about a guy who used a fox body mustang springs. can't remeber front or rear.

 

I would measure the stock springs, then go looking at springs for other models with the same outer dimension and height. Then opick out the spring weight you want. If you are drag racing, are you sure you want a hard spring?

 

The front springs from a 90-9? Nissan 300ZX will fit in the rear and will also lift the car considerably. I think I needed to cut 3.5 coils off to match stock height when I had them on my car.

 

You can use AFCO 5" diameter springs. They can be found on EBay at 11" lengths and you can just cut them down to around 9 inchs. Probably want something around 250Lbs. They can be had for around $30 each.
