So looking over the brake upgrades that people do I get the upgrade to the 944/924 turbo brakes. However for those of us that are still on a bit of a tight budget, I wanted to know your opinions on the following.

http://www.jbugs.com/category/vw-disc-brakes-conversions-kits-super-beetle.html

Looking over part numbers and such, I believe the brakes on our 924's are taken from the Super Beetle, if this is the case the above link is an upgrade to disk brakes for the back which could improve our stopping distances and cooling without breaking the bank.

Thoughts????

Band aid solution at best, even if it fits.

Conversion parts that hard to come by up there? If it were me, I would slowly collect the proper components as budget allows, and do a little work with pad selection in the mean time.

Also might consider ducting the fronts. . .the one time I tracked them they got, um, rather warm.

The front bug brakes will not fit. the bearing sizes and offset are different. Also the bolt pattern is different. The bug pattern is 4 x 130mm VS the 924 which is 4 x 108mm.

The bug rear kits might fit but again the pattern is different.

Keep in mind once you add bigger brakes you may also want to box the control arms, redo the bushings and will need heavier front springs and dampers. (which usually require custom front strut housings if you plan on using changeable inserts.) All of the extra force from braking gets transferred into these components.

A cheapo brake upgrade for 4 lug cars is to use calipers of a early 90's A4 Audi (also fitted to Golf GTi's I think) and the biggest VW T3 rear drum along with converting to a standard front rear split for the brake lines. Use the standard 924 wheel cylinders to get a good balance for front to rear braking.
I use this on a race car and with R spec tyres I have never found the brakes inadequate.

Also, to get a better (firmer) pedal feel I use a Turbo master cylinder with a hydraulic proportioning valve

If your braking balance is about right the difference in braking distance will be about zero iwth uppgraded brakes. since its no problem to lock up the brakes on a standard n/a on track even with R compounds. What you will get is getting rid of the constant adjustment on the drums, which is really annoying. And probably better pedal feel, its always spongy on the drum setup, especially if its setup for track.

If you overheat the brakes you either have one of these:

- Shitty condition on the mc/calipers or rear brakes /badly adjusted drums.
- Wrong pads for the job
- Wrong brake fluid
- Wrong braking technique
- Much more HP than the stock 125 n/a

The beetle thing is interesting, you can buy them without bolt pattern and do it yourself. But it will be some fiddling to get the correct braking balance, there is a risk that you will actually get worse braking distance until you get it right.

If I were in your seat I would first of all focus on what problem you want to solve. And probably end up with the 931/924S/944 setup since its much easier to get it right.

Yep, convert to 5 lug vented rotors front/rear. Will need to get hand brake line too iirc.

Definitely want to go the 5 lug upgrade route in the future. The car is so well balanced, but my master was bad, I have it rebuilt and waiting for the snow to go away before I install it. It is the constant adjustment that I am looking to move away from.

Thank you all for the input, as always it is much appreciated.

I put the 931 vented set up on the front of my 1983 but used 5 stud drums from a beetle specialist on the back, quick and easy to do, doesnt need a new handbrake cable and I have very strong brakes that are well balanced.
