Any chassis solutions to mitgate outside wheelspin?

[Waterfan]

Hi all, longtime lurker (2013?), new owner of bone-stock CPO 2014 Oxford White with Recaros and Nav.

At only 4 days and <100 miles of ownership I find the FiST to meet or exceed my expectations in every way, especially every corner I can take "at speed" (taking the non-direct route to and from work helps )

Beyond decent tires at the right pressures* and street-friendly alignment** and short of aftermarket LSD, are there any other chasis modifications than can mitigate outside wheelspin?

Specifically, I'd like to tap itno the community wisdom on anything related to the following:
-The stock setup already "feels" completly flat, so bigger antiroll bars won't help?
-Maybe upper and/or lower, front and/or rear chassis bracing?
-The ONLY thing I don't love about the chassis is the "jittery" rear end in long sweepers, mostly due to the "very" short wheelbase I am not used to or is there an opporunity to adjust damping, spring rates to "stabilize"? And mitigate outside wheelspin in the process?
-Whatever else I am not thinking of...

Or is this merely a case of PEBSASW? (Problem Exists Between Seat And Steering Wheel ) aka "Straighten out first, moron"

*I'm looking at swapping to 16x7 lighter weight wheels and 205/45/16 tires (maybe RS3s?) when the excellent (to me) stock REs are done.
**My FiST is "just" a daily driver, but I like putting my foot down midcorner, not interested in negative camber that makes cornering awesome but causes premature tire wear. (What's a good middle ground for the FiST that does not compromise the overall EXCELLENT stock chassis setup)

Apologies for the very dense post, kind of excited to join the community for realsies!

I run SCCA and the eibach pro springs (drop like 3/4 of inch), regular Fiesta front sway bar (thicker than STs), stock REs inflated to 42psi front/32psi rear has kept me planted with times besting cars with coilovers... ($300 total investment)


Now that I have an LSD, it's a different driving strategy... brake late, yank wheel, keep floored..

Pretty sure you aren't spinning your outside tire in a corner... you're frying your inside tire.

You need to do everything you said you don't want to do to fix it. Tires are a bandaid and LSD is the cure.

This is correct. You're spinning the inside tire, not the outside. LSD is the only true fix.

Oooh, I have to check my ears. Seemed like the outside tire, but I'm sure you're right and I just don't really know what I'm experiencing with only a few days of ownership. Maybe I just needed confirmation that "LSD is the only true fix". Thanks all.

If you have only had the car a few days, make sure you try Sport and TC off modes. Try enthusiastic driving in all three modes, learn how the nannies behave. My granny could drive it fast with all the nannies on.

Even with all off, you still have torque vectoring that will apply the unweighted front wheel brake. So inside wheel spin can be a "regulated" problem, but I have never had outside front spin in enough in turns to notice.

My experience is that I was not able to learn how to drive my car at its limits without going to a track, and even then, its not easy to drive as capably as the car allows. I really want to modify it more, but the money spent learning to drive it better first has been very satisfying.

Great advice, I appreciate your input.

All great advice, great questions asked as well

LSD gets my vote as well.

Other than that a tune to reduce torque in 1st and second, maybe a bit in third if you have any issues there would help and should make the car a little faster since not spinning the tire, brakes being used as much by the torque vectoring.

------------------

More negative camber, unless really excessive and not enough air in the tires, does not cause much if any added tire wear and if you regularly run through your favorite twisty roads, autocross, etc...it can add life to them compared to running stock camber.

But adding more to the front and leaving the less than optimal rear camber could cause an even slipperier rear end.

The way to fix the rear end is not so simple until somebody comes out with quality camber plates as the stock rear camber promotes a loose rear end, on purpose, I do not prefer than on higher speed corners and I take my car to very high speeds on track. It was a pretty intense project but I changed the rear camber to what I wanted to run and the rear of the car sticks like glue no matter how fast I corner.
