Big front brakes.

What is the biggest brakes I can fit under 15" comps, 4 stud and have stick on wheel weights on the inside?

[John]

288mms and v6 calipers should just fit, might have to get them re-balanced though.

A friend of mine has 300mm high spec discs using 16v calipers under 15" Mo's iirc.

[xe_nova9]

Have you got any pics Nick? Do you know what the discs are from? what vaux do the 288mm's come on?

I have vectra v6 brakes fitted, just snuggle nicely under my 15's and stop VERY well. can get pics if you like?

Have you got any pics Nick? Do you know what the discs are from? what vaux do the 288mm's come on?

The 300mm Discs were made by the company "High spec" there damn expensive and he had a fair bit of modding to the caliper to make them fit iirc. Your best of going to LMF vauxhall as they'll do you a v6 caliper and 288mm disc kit drilled to four stud for fair money and they should have no bother going under mo's as that kit goes under gm 15" wheels and mo's have more clearance.

Nick.

[AlanH]

^^ what he said, mine are 15" mk4 astra wheels and clear fine

[xe_nova9]

Yeah please mate pics would be good, Are they standard vectra v6 calipers and discs/pads? Have you got stick on wheel weights?

[Adam]

288s fit EASILY under Mo's.
Mo's are a huge wheel in terms of brake clearance.

[AlanH]

yes standard discs/pads just drilled the discs out. not sure about wheel weights, i'll check when i get in later and get some pics

[xe_nova9]

Ok so what do 288's come on? Eg if I was to go down the scrapyard to get some what car would I be looking for?

[AlanH]

v6 vectra/omega/calibra etc.

[Stuart]

omega calipers wont fit without faff

[xe_nova9]

oh, so 288mm=v6 brakes?

[novarally]

Width and offset of the MO's will also make a difference as to how much brake clearance you have.

On an ET49 and 6" wide rim you will be able to get the 288mm V6 brakes in OK.

Anything bigger starts to be a problem unless you use spacers.
