two months ago I installed my KW v3 coilovers i got from hypermotive and I love them. My car handles completely differently now and I want it to handle even better. Whats the next step in suspension mods? Sway bars? Control arms? Brakes? What will further increase my corner carving abilities.

 

Hey brother, tires will help quite a bit. Next look into the UCA to correct your pinion angle, your UCA will help with wheel hop more than anything if you suffer from that as well. Look into brakes as well, there are a few options with brakes that are affordable.

 

Define what "better" means to you . . . what does the car do now cornering-wise that you wish it didn't, or doesn't do as well as you'd like?


Tires and wheels as wide as you can reasonably fit and as grippy as you feel comfortable buying from time to time. But don't go so wide with the tires that they're being squeezed down on rims any narrower than "measuring width" for that size. With 4.6L not forced induction - no tire size stagger, please.

Depending on what your alignment currently is, more aggressive camber settings.

If you're going to get out on the big tracks for HPDE/open-tracking, brakes should be a top priority, particularly having track-capable pads. For street and autocross, a good performance street pad is all you'll likely need.

Control arms are further down the list unless you're starting to get wheel hop. If/when you get to doing rear LCAs, you'll want at least one end to be a spherical joint of some sort.

Pinion angle tweaking is further out than that as far as cornering is concerned. The only exception I can think of might be if you're running SCCA's "Pro-Solo", which is autocross with a drag-race start.

Well i am currently running summer tires on wider wheels, but I do want to be able to corner carve and do some track and auto cross and not have a hard time keeping up with the smaller cars on the twistys thats why I figured sway bars or brakes next?

 

Sizes? Mfr/model? Wheel width?

It still comes down to seat time, and then tires/wheels before the rest. The exception being brakes, and this specifically out on the big track.

Swaybars AND control arms. They both made a noticeable improvement in my car. The control arms make it feel more stable in the corners and the swaybars reduced body roll in the corners.

Invest in a HPDE School... BMW Club or Similar.. Best handling mod you can do!

 

A couple of questions first.

What wheel (dimensions) and tires (size) are your running?

How lowered are you on the coilovers?

Is your sig complete or are you not listing other suspension mods?

My suggestions and in this order.

MM camber plates with -1.8 degrees camber

18 x 9.5 wheel with summer only tire that is soft and grippy 255/45/18 or 285/40/18 square set up

Watts link

Adjustable sways and adj endlinks

Front LCA

Rear LCA and UCA - adj and one end on the LCA needs to be rod-end like

A arm brace

Subframe connectors

 

I took the advice you gave me before about the camber and I love it I have a 2008 gt with rota grids that are 9.5 all round and bridgestone potenza summer tires

 

i would love to haha
