Rear anti roll bar

[synthedup]

Hi All,

I would like to stiffen up my rear end as I get a fair bit of body roll when i corner hard.

Will upgrading the drop links help? or can I fit a stiffer anti roll bar? maybe from a M3 or similar?


Thanks

Different drop links won't help, only a stiffer anti roll bar.
The rear m3 antirollbar doesn't fit.
You can get one that fit's from H&R (or another aftermarket supplier)

I'd suggest viarga

If you're on M sport then H&R is the only other option, I think. Worth doing ARB bushes and drop links while you're there.

What are the roads like round your way? Stiffening the rear arb will result in less roll during turn-in but you'll be more likely to spin the inside rear as you put the power down, and the car will tend more toward understeer.
In terms of grip you're better off looking at different springs and dampers, and then maybe playing with the front arb as stiffening the front will make the car oversteer more

Stiffening the rear will make the car oversteer more and the front will make it understeer. You are right about traction on bumpy roads though.

As with all these things though it's best to uprate both ends so I'd get both H&R bars, they should have some degree of adjustment so you can fine tune the balance towards under/oversteer.
