Compbrake Eccentric Topmounts

Cleaned this up as it was getting cluttered:

Back by popular demand from Grant at Ace last night

Original Post:

Been on the phone to Compbrake about their eccentric topmounts, and they're very receptive to sorting us out with a good price for a groupbuy.

For those who don't know what these are; http://www.compbrake.co.uk/Parts-by-Car-...d_398.html

They essentially permit slight 'tilting' of the struts, so you can set the car up with a bit of camber, or a bit of caster. If you know what you're doing, setting the car up with camber can improve the front-end grip when cornering hard, because the car will 'roll ONTO the tread of the tyre as the weight shifts in the corner. I personally will be setting mine for maximum castor.... I cba to explain this, particuarly as the following link will explain it better than I ever will...!

Tofit these, you do need to drill one new hole to secure these to the chassis; its pretty basic stuff, took me about 10mins to have these bolted in!!

As far as I am aware, you can only run these with coilovers...

I've already got a pair on the '6 and they make a hell of a difference to the grip. Couldn't go back now. I've only had them on a few hundred (hard) miles so cannot comment on longevity at this stage, but will be happy to keep everyone up to date!


To answer some questions that came up on the original thread;

1. These are £153 including VAT & delivery from Compbrake if buying individually (£7.80 delivery estimated on the site to my address)
2. I don't know the longevity of the bearings, but they are easily replaced, and the replacement bearings are a fraction of the cost of standard oem mounts.

These are the compbrakes mounted on a 306:






For comparison, these are the baker BM alternatives:



I should also point out (taken from the BakerBM Website):

BakerBM Adjustable Top Mounts £220 + VAT. Bearings, top spring pans and sleeved nuts sold separately. Please email us with your requirements.

You can see what the 'maximum adjustability' relates to the actual hole in the chassis, rather than the topmount design.

If you still want more adjustability, I've seen plenty of people modify the chassis like this:





I've spoken to Compbrake; based on an minimum order of 5, they can do these at £90.75 + VAT + delivery each.

Please note these are only compatible with coilovers.
