spohn coilovers

Anyone running the front coilover street kit?

Thoughts?

Thinking about it for my daily driver, just wondering how it would hold up / ride?

Re: spohn coilovers

i have it, but the car is not my DD. I have no issues, but i would highly recommend a STB if you dont already have one.

The kit will limit you front tire size a bit, if you are running stock wheels you are fine, if not you cant go much more than 5" of backspacing.

Is there any reason you want to run them? their main purpose is weight reduction, no major handling benefit that a good set of conventional springs will take car of. They do however, make it a lot easier to take the front end apart, no more spring compressors

Im thinking about swapping my coil-overs for ground controls weight jacks, solely for the purpose that i want to run a larger front tire.

86TA, let me know if you decide to sell your spohn coilover kit.

You will be able to run softer springs to get the same performance as the relocation is much more optimal.

not sure im following you.
Im running 325lb springs up front, so yes they are softer than a conventional spring, but its a matter of leverage because of the new location of the spring, again leading to weight reduction. Not sure if there is added performance because of the relocation of the springs.

Re: spohn coilovers

I don't see how the car would perform better with the coilover, but I've heard the ride is better. I don't have the technical expertise to evaluate that, but I know the stock spring rate vs the coilover spring rate is much stiffer for the same resistance because the stock a-arm acts as a lever and 'increases' the pressure put on the spring.

Exactly right.

You can run a lot lower lb/in spring with an outboard mounted coilover than you can with an inboard spring pocket and get the same level of handling.

Or you can run a high spring rate in a coilover that would be too harsh for a stock spring location equivalent.

The weight loss is minor, but the relocation is the real benefit.
