Spindles

[1EvilV6]

Just bought an 86 GN. Previous Owner installed 1" UMI and Bilsteins. I want it a little more down - but not too aggressive. Thoughts?

UMI sells 2” lowering springs as well or you could go coilovers.

Yeah - I looked at the Coilover route as well! I'm just looking for a decent stance, with a little better ride quality. I know these Cars "are what they are" but I'm going to drive mine and enjoy it. Thanks for the input - much appreciated!!

For what it’s worth the standard regal front springs are 350 lb/in.
Regals with the touring package (GN’s, T-Type’s, Turbo T’s and the like) have 422 lb/in. front springs and 118 lb/in. rear springs.

The UMI Performance springs are 600 lb/in. front and 130 lb/in. rear.

I had ATR handling springs for a long time with Bilstein shocks and I thought the front was just a tad floaty.

By the wire diameter of the ATR front springs compared to the UMI springs I would say they were in the 525- 550 lb/in. range.

15” tires ride better than 16s, 17s and 18s. I didn’t notice any difference between 255/50VR16’s and 255- 285/40ZR17’s and am looking forward to 285-295/35ZR18’s.
Tires with a lower speed rating have a softer sidewall and will ride better.

I know ride comfort is subjective so I hope this helps.

Thank you! This is the exact reason I joined.

There are quite a few posts about Moog springs and rates.
There’s one about a lighter set of springs and a heavier set. I believe they’re both 1” lower than stock.
Just search moog, there’s a lot of info.
This is the first one I saw with both sets of springs listed.

I'll look into this for sure! I've got a TON of stuff I've already been researching. This is one on my list for sure

Moog 5660 is just under 600lb/in and drops the car about an inch. CC651 rears go well with it and you can still get them from the corner parts store for under $100 a set.

Too much drop and you're dealing with alignment problems and a lot of bumpsteer that starts getting expensive to remedy. If it's a driver, don't go overboard and ruin it. If you want more than about an inch drop without having to dive into aftermarket arms and bumpsteer correction, then drop spindles are the way to go.

Thanks for the input! Yeah - I'm going to drive it as much as I can! I'm going to keep it as simple as I can.
