Largest discs that can fit behind NA6 rims?

Postby nath » Sun May 25, 2008 12:13 am

Time to upgrade the rotors and just wondering if I can get NB8A items behind the stock rims?

Yes you can. The NB8A brakes are the same as NA8; and NA8s come standard with 14" rims... 8)

boags is correct. i upgraded my na6 to the na8/nb8a brakes and i still run on my 14s.

remember tho that you can't just upgrade the rotors, you also need to change the calipers and brackets.

Thought you could still use the same calipers just need brackets and pads.

you can , but it's not the best solution as you will get uneven pad wear. if you choose to do this, you also need to swap them left to right and vice versa. i think. it's been discussed a fair bit... matty seems to know all the ins and outs of what works with what and what fits where.

Good point. Its probably a good idea to get them reconditioned while they're out.

Another point is, whats the point of upgrading to the 1.8 disks anyway. The 1.6's are more than adequare for a stock car at the track and a boosted car on the street. If you're tracking a boosted car the you'll need the sport brakes anyway so the 1.8 brakes aren't really worth the effort imo, I've been through this situation before and stuck with the 1.6 brakes and better pads and rotors and they're fantastic, that is until I buy bigger wheels and then eventually big brakes.

If you do upgrade, do front and rear at the same time.

well. Thats true but if you have dríven an NA6 with the upgrade I'm sure you will change your minds. On a racetrack you probably have a very valid point.

on the street & The NA8 or NB8A brakes have a much better initial bite. brakes feel as though they are how they should be.

I only have the fronts of a NB8A'.....but it makes a big difference one day "ll have enough to change the rear as well.

does it make any difference stopping quicker ? It probably doesn't. But nor do sway bars. They just give you a more secure feel when you are cornering hard
