sway bar sizing for track use

[MatRacer]

Hey!

Here is my actual setup:

front:
300lb/in spring
Bilstein sport shock
22mm ST sway bar
M3 style link kit
stock alignement - no camber plate

Rear:
500lb/in spring
Koni sport shock
19mm ST sawy bar set to the soft position
Stock alignement - no adjuster

Here in Quebec roads are pretty bad. Same thing for our local track. Considering that, the "soft" spring rate feels ok. The rear is a bit happy especially on bumpy corners where I have to accelerate very late in the corner. During the winter, I will definately add rear toe and cmaber adjuster and camber plate. I'm looking at reducing the rear bar and maybe removing it. However, since I'm running solf spring, I'm not sure of the result.

You suspension guru, would you recommand running 16mm rear, 14,5mm or maybe stock 12mm? Can I remove it without messing it all up?

Thanks!

I would get your camber and tow dialed in, but my guess with the s52 you could use a smaller rear bar.

Soft springs will let the car roll chewing up tires with out additional camber. A matched damper has a lot to do with wide quality too, and help the control of the spring to put the power down better.

Still running soft bushing?

Running solid subframe frame and diff bushings. TAB are IE polys. Front CAB are solid offset.

Bars are kind heavy for road use. Spring rates are on point for dual purpose.

If you still have the stock sway bars, try them back with fresh bushes and lube.

A happy rear needs more dynamics travel. So, looser shock, lesser spring, more toe in, more LSD grab etc. If you have an open, or borked diff, unbolt a rear sway link and see how it reacts.

Don't forget to check preload. Car on level ground should be able to unbolt and remove the links by hand on all four corners.

Completely removed my rear bar last week and went to a lapping night. It was rainning. Usually, I have a hard time putting power down under rainy condition,but this time it was way better. I felt a bit more roll when the track dryed late in the night. Camber plate will definitely help.
