I have a FBI 2007 335xi MHD stage 2+ and I am toying with the idea of fully rehauling the suspension to make the handling as good as the power. Shocks and coils have already been done. Is it worth it taking into account that this will be a frequently, but not dedicated, track driven car. I also use it as my daily driver. I was looking at the turner motorsports upgrade that I pasted down below. Could anyone tell me if it?s worth it and if not, what upgrades should I do for suspension. Thank you.

Unless it is a dedicated track car, the Turner package is absolutely not worth it.

With all the spherical bearings, it will wear out at an accelerated rate during daily driving, and NVH will be much higher.

You have to realistically ask yourself, how often will you actually go to the track, and what is the overall goal for the car?

If you only want to do HPDE days, then just do new OEM arms with fresh rubber bushings (or swap them to Poly bushings). I did 17 track events in 2025, and plan on doing just as many this year, and thats taking into account moving towards Time Trials.

The Turner parts can offer alot of adjustability, but assuming you havent been on track yet, they arent anything that would hold you back. Rear camber and toe are pretty adjustable from factory, and only real limitation for a mainly HPDE car is front camber.
But if you're just learning about being on track, focus on driving the car in its basic form.

I'm sure what will really hold you back (that holds most of us back) is heat management.
