Title: 330mm convertion probs
Post by: billybobbooth on May 16, 2013, 04:25:33 PM
Hi guys im sorting out my brake conversion I so far have

18" alloys
330mm calipers radial not lug mount so bracket is easy to make

My question the calipers are brembos off a alfa gta but im after a disc I can just bolt on dont mind some machineing of the centre but not of the bolt holes

Closest 2 discs with 114.3 patern and 32mm wide are evo 8 at 320mm or 370z at 350mm

Othes are around the 323 mark but only 30mm wide

Will the 370z discs fit in a 18" wheel as there 19" stock on 370Z Im happy to place fit in wheel but dont wanna have to buy a disc thats no use to me. Or am I better off using a 320-324mm which I know fit in 17" as I know I can go to at least 330mm with the wheels.

Always hard to say what will fit. Its all dependent on how much room is under the wheel. I\'m running 356mm KADD kit under 17in team dynamics prorace 1.2 . I could email the wheel maker with a drawing of the brakes before I comitted to both.

Can\'t see you having issues under 18in wheels with the 350mm discs. Are you machining the bells for the discs too ? There are quite afew things to consider. Whats the bore size of the bells on the 370z disc and the offset ?

The centre would need boring out not a prob as my wife brother has a digital machine at work for doing this.
The hight of the disc is shorter so the disc will sit further out but I have spacers on snyways as I have a wide arch kit going on again not a problem as gives more room for making a bracket for the calipers.

Ive just been looking around to see who makes a big stock disc with the 5x114.3 stud pattern this way if in the future I cant get hold of a set og lightweight discs I can always just buy a stock disc.
