my suspension is shot. I believe it's original. I went with some kyg gas shocks in the rear, just the basic ones. I need to replace my rear coils as well. I have around 300 hp, 373 limited slip posi, 2600 stall, turbo 350 with a shift kit, 245/45/17 tires. Street use only. Any suggestions? thanks, kyle

Personally I like the cargo rear springs. The more weight thats added to the car the more they hold, Regular springs start to sag with a little weight. Regular springs will also lower a cars stock height, Be careful that your tire s dont rub.

Where can the cargo springs be purchased from? and do they have the same effect from take off acceleration so some torque isn't lost? thanks, kyle

Hey. Advanceautoparts.com and autozone.com both have the rear springs you want. You can tell cargo (also called Variable rate ) spring from standard spring because cargo spring have more coils at the top of the spring.
Advance auto parts # CC627 $84.99
Auto zone # RCS627V $63.99

For the REAR: you can try coil over springs. I use 14" x 150 lbs for my 79. It sits good. Here is the link and summit part number:
http://www.summitracing.com/parts/HAL-14-150/

I have a set of 12" x 150 lbs that are too low for my car. They're free to you if you pay shipping.

On the 1980 wagon, I'm using moog 5391's on the rear. A bit high for my taste, but I'm hoping they'll settle after a few miles.

Fronts: on the front of both my cars, I went with dropped 2" spindles. If you go this route, be sure to replace the front springs with new replacements. I did this with my 79 and had no problems. With my 80, I put the spindles on and used the stock 30 year old springs. BIG mistake... the springs were so shot I was rubbing tire at every hump in the road. This morning (the 1980) I replaced the 30 year front stockers with moog 5664's. The new spring picked up the front a bit with the 2" drop spindle, but being a new spring, it has resistance, and my front tire doesn't rub at all (195/75/14) on turns, bumps, speed humps, etc.

the 1979 FRONT: 2" drop spindles with moog 5660 FRONT springs and REAR 14" x 150 lbs QA1 coilover springs. Car sits good with a slight rake. I'm running 17x7 225/55/17 fronts and 17x8 245/45/17 rears

the 1980 FRONT: 2" drop spindles with moog 5664 FRONT springs and REAR moog 5391. Car sits with a bit too much rake due to the rear springs being too stiff... hopefully it will settle. Front bumper molding at 19" from ground and rear bumper molding 21.5" from ground... about a 2.5" rake. A bit too much for my taste. The tires are the same front/rear on 14x6 wheels with 195/75/14 tires.

Those springs are cheap!? Are coil springs normally that inexpensive? And what height is a normal stock coil? I'm running some sticky street toyo proxes 4s 245/40/17 on a set of crager ss wheels
