I hope someone here can help me on this predicament....

Basically no-one does a big brake conversion for the 21 Turbo - so I decided...and rightly so I think - that if I'm going for a big power hike that I'm going to need good stoppers to compliment this - especially if I'm going to be doing track days, visiting the ring etc.... Standard front calipers are single pot...

So anyway....I've got my hand on a pair of Clio V6 330mm x 30mm discs that have the same stud pattern/offset as standard 21T discs - now I need a set of calipers/pads/brackets to go with these.

Problem being - the 21T for whatever French reason - have a fairly big bolt spacing - 125mm on the hubs to mount the calipers.

I'll let the pictures below explain the rest....

Reverse side of above perfect position...the problem arises....


People have said well its a radial mount so just move the caliper round a few degrees.....well no unfortunately not - its impossible because the hub mount protrudes over the inside of the disc that much that this is what happens...

Move it to the left..


Move it to the right...


As you can see the inside of the caliper touches the disc & the pads no longer sit squarely on the disc and foul the hub mount, as well as the edge of the pad being over the outer edge of the disc.

So my question really is how the hell am I going to solve this....I think that I need to go with brakes that have a much smaller mounting centre or a larger mounting centre measurement. I really do not want to start talking about welding new brackets to the hub etc.

Will I manage to get away with using 152mm mounting centre radial mount calipers - bearing in mind they 125mm mounting centre standard - by my calculations it will ONLY just do it - is this enough to be safe tho??? Porsche caliper is a 130mm mounting centre caliper in the picture.



I am after at least a 4 Pot caliper - possibly 6 depending on price - I'm running 18" wheels so outer clearance shouldnt be a problem!!!

Any help or recommendations gratefully received as this is now the only thing stopping me getting it MOT'd which I could do with doing in the next 2 weeks!!!!

Thanks in advance for any help!!!
