I have a 2024 F57 JCW.

I don't track it and don't want to drive on the street in such a manner as to lose my license. Just hard, sporty canyon carving and the like.

The F57 already has a lot of extra bracing vs the F56, and yet braces like the Cravenspeed "Big Pair" and Way Motoring's "Chassis Bones" are advertised as F57 upgrades.
Has anyone used either of these (or similar) and found a difference on the street?

Also, might swapping-in a thick aluminum braces vs the stock steel braces save "significant" weight?

 

I’ve often wondered this myself, if there was any tangible difference with the Cravenspeed braces.

 

None of those braces will reduce weight. If anything, will add a slight bit.

The best handling modification for the cost will be to add a bigger rear sway bar.

 

I have an F56 and installed the Craven Speed Big Pair and was very surprised with the improvement, the Way Motor Works is also good quality and a little less expensive if I remember. I also have an NM 25mm rear sway bar that was installed before the braces.

 

+1

 

FWIW: The best way to improve driving performance is to save the money spent on aftermarket add-ons and sign up for a good driver's school.
Just sayin'

 

Thx.

Any recommendation? I know all the main options, but some folks say too stiff is no good for the street. (Though maybe that's more in regards to the front bar?)

 

Still wondering if a stiffer bar will be noticed with street driving only.


Any additional thoughts?
