Csi rear anti roll bar

Steve I will PM you later.

A little extra info: On the 840s this increases the rear dia. to 17mm from 15.5mm, if the front is added as well it will go to 27mm from the stock 25mm. Early 850 owners need to pay attention on the front bar as it's a different config. if buying non-$tealer. I did this mod on my 840.... taken alone it's a noticeable improvement, when combined with stiffer springs, bilsteins, (and 8tech's all important tower reinforcements!) it's the total rear package IMO. Good luck with your sale.

... also need to remove rear boxes and diff to fit. For this reason I returned the one I bought from the dealers. Fitted the front one though, as that was a doddle

Now, if the car was in bits anyway, I'd consider fitting one, but the cost to dismantle and then refit outweighed the advantage of having it - for 99% of my driving anyway.....
