I thought about putting Eibach springs on the SHO but decided not to its snows in MD. I'm actually looking at trading that and the fusion in on either a truck or some type of SUV not sure which yet..

Yeah I could imagine it would be pretty bad my 15 GTPP with the spring rate I run is not a great ride either but then again I only drive it 1 to 2 times a week if that.. I have a SHO and a ecoboost fusion I drive daily both completely stock and they'll stay that way

What springs and dampers do you have?

What springs and dampers do you have?

I have Stance XR1 coilovers can't remember exactly what spring rate I have it at home its something like 13k frt. And 18k rear and the stock set up I believe but don't quote me was 10k and 15k

I did find it strange that the higher rate was in the rear usually the higher rate is where the higher weight of the car is for instance 55/45 would be like 500lb/400lb. Has something to do with inboard spring outboard shock.. not sure I will look at the rates when I get home but I think the ones I quoted were close

Stock is 3 / 13 in kg/mm.

My handling setup is 4.4 / 17.5 for reference. Your coilovers are probably hurting more than helping, tbh.

And yes the rear is much higher because of the spring location and it's resulting motion ratio.

I know on the TRACK it was good.. I've been RR for about 15yrs now but you might be right I noticed the car turns in faster now but with that being said it slides around a little more before the tires are at temp then before

Fwiw, the better racing coilovers (Ohlins, MCS, Cortex/JRZ) are typically being run in the 8-11k range up front. I'm not sure if what you have has the tuning/valving to keep up with that spring rate.

The stance are inverted monotube they have 16 adjustment 1 being softest.. I had KW V3 on my RS4 these feel about the same as far as rebound quickness.. OHLINS are really nice I've had TIEN, had roush factory with the car they sucked no valve adjustment on the ones I had my car is a GTPP bit was built at Roush then sent to me in Md. I've changed alot with the car as far as cooling and the Blower.. the Roush calibration was super concervstive

Still waiting to get out with the DSLR, but grabbed a few phone photos. Put about 30 miles on the setup, no rubbing as of yet. Still need to put it through some hard corners to confirm it won’t rub at all. Have to setup an alignment and then I’ll go shoot it.

how did you figure out your issue with the clearance?

You would have to grind down the top of the caliper or switch to smaller calipers.

Looking at running a square setup

20x10.5 et42

Will I have issues on the front? Probably run a 275/35

Car is a GT so has the brembos

If your gonna have a 10.5 inch rim why run a 275? If you want to run that small of a tire just get a 9.5 or 10inch rim and avoid clear issues all together

More for the concave look what tyre should I be looking at I wanna stagger tyre size

For a 10.5 wheel you should be looking at a 295 or even a 305. If you want to go staggar then I would run a 10in wheel up front and an 11in wheel out back. Or 9.5 and 10.5 depending on what's available. Also if you do 19's they will open up more tire possibilities should that matter to you vs 20's.
