twin vented rear discs...
« on: 29 October 2008, 20:57:38 »

is it possible to have the calipers and discs off the front of the omega and put them on the back?

just wondering as it'll help the old barge stop a bit quicker (it's 2.5 so it'll be 296's on the front and 286 on the rear but twin instead of single) :P
thanks

facelift rears are vented.

If yours doesn't stop quickly, there is a problem.

I think you stand a chance of upsetting the front / rear bias and will tend to lock the rears up too easily if you put front discs etc on the back.

just checked and it only applies to the 2.6 and 3.2

if it's on the 2.5 that im on about swapping to the vented rears then would it matter? think the 3.2 and 2.6 only have the same 296's that the 2.5 and 3.0 have which would make it the same brakes on front and rear between facelift and prefacelift....

might experiment for the improved braking on my mig and for the factual benefit of oofers! lol

the braking power of the front and rears are not the same..rears utilizing a small portion unless the car is loaded..So will not be very effective on brake distance.. Better let the car checked by a proffesional from the group may be some other problem causes the picture.. :-/

well what about if the fronts are being uprated to 308's for example, surely it wouldnt really matter aslong as the abs can cope with it

Very good point. The brake balance may well be wrong if you fit the front setup to the rear, and that's not a good thing.

I'm sure a facelift V6 rear caliper and disk would give you a vented rear without issues but personally I wouldn't bother unless I had problems with the rears overheating. It's a fair bit more unsprung weight for a start.

I had an interesting experience..if you want more effective brakes play with the compression ratio of the engine itself..on my previous car I modified the engine increased the comp ratio with some headwork..and brakes become superb.. :)
