Rear springs question.

When I was first building my car, I opted for Ford racing springs. I forget which number they were, but they were a 1" drop in the front and a .8" drop in the rear with a fairly tight spring rate. The car sits and feels fine, but there seems to be a tad more wheel gap in the front than in the rear. I also just bought new wheels for my slicks, and the offset puts the outer edge of my 26" slicks just under the outer wheel well lip. I had to adjust my shocks so the tires wouldn't rub during my launch. Plus I have VERY little room with my 274/40/17" in the rear, with the quad shocks flipped, there is just a hair of room.

I would like to eventually go with 4.10 gears and a 28" slick, but there is no way I could get those to fit with my current setup. So I am thinking of swapping out the rear springs. I figure maybe a slightly taller spring to make the ride height a little higher in the rear, plus it would give me more room for taller slicks.

Without breaking the bank, what would be a good rear spring to go with on my DD? I would like to keep the tight feel of the car on the road, but have room for the slicks and still be able to hook at the track....something I am having a hard time doing now when I spray out of the hole.

It is an 88 Coupe, with Steeda tubular lower and fully boxed uppers with urethane bushings. Stock quad shocks, flipped. Strange adjustable rear shocks. Stock rear sway bar. 3.73 gears. Steeda full length subframe connectors.

Thanks.

I thought about that, but I have heard a TON of bad things about those control arms. I talked to one company today that said they stopped carrying those because they had a bad habit of breaking on people.

I do love the idea of having them adjustable, I just don't want to have any issues in the future with them not holding up.

I was thinking about those adjustable style control arms, and it got me thinking...

Wouldn't an adjustable arm like those actually change the spring rate? I mean, the control arm stays where it is, and by adjusting the perch up, you are actually compressing the spring more. Wouldn't that effect the spring load?

I would think that the more you adjust the perch, it wouldn't raise the car as much as it would just compress the spring more. So for every turn of the perch you would raise the car a little, but you would also make the spring tighter.

Or am I over thinking the whole thing?
