Hello,
What is the biggest standard easily available sierra front disc that fits 13" alloys, I had a quick look at ebay for sierra disc sizes, there are 240mm vented discs that should fit no problem and then there are 260mm discs would these fit?

The discs on the rear are solid 253mm sierra stuff with a small mod to clear the spring, so ideally I would like to use the 260mm discs

Cheers
David

I can't tell you the answer, but I do have a set of the 260mm calipers in need of a good recon that you could have for a couple of beer tokens....

Thanks mcerd1,
I will do a few measurements and try and see if the 260mm discs are the way forward

Cheers

Hello all,
Before I try and cram the very largest brakes under the front end of my 13" wheeled mini, what do I actually need, using standard sierra stuff, I have the option of 240mm vented discs, 260mm vented discs (which I think will fit) or would solid discs 240mm or 253mm do the job. What ever I fit I will use the wilwood midlite 4 pot alloy calipers in vented or solid disc configuration and a quality performance pad to suit

The mini is mostly spaceframed but all steel panels, not sure on engine yet, it could be bike engined or car engined, I estimate it will weigh approx 550kg~ 575kg with a large bike engine and approx 650kg~700kg with a car engine

Intended use would be mainly road and occasional trackday/hillclimb/sprint as funds allow

Cheers
David
