Just a little FYI.

21.5 mm p/n 31 35 6 722 751
22.5 mm p/n 31 35 6 722 752
23.5 mm p/n 31 35 6 722 753

The bars are $132.00 and are in stock at most of the BMW PDCs.

 

As GS does not allow changing the rear sway bar - what are the advantages of just changing the front?

 

two thoughts:

go smaller and increase the effectiveness of the rear bar, similar to installing a larger rear bar, adding rotation.

go larger and maximize transitional response and effectively increase front tire contact patch by keeping the car flatter.

Trade-offs:

smaller, less crisp turn in, more body roll. Less wheel spin on corner exit

larger, more understeer, more wheelspin on corner exit. Higher speed through corners.

 

I thought the "twig" front bar off the Mini One was 17 mm? Or is 21.5 the smallest?

 

Oops! I just noticed the title of this thread is for the R56. i was talking about the earlier models.

 

Thanks for the PN's
