Brake upgades ???

[gareth]

The 280mm G60 disks are too small,both in diameter and thickness

The 302's were the smallest I've managed to get to work with those calipers.

I have a contact who can make some anodised caliper brackets in HE 30 for £95ea +vat if that's any use.

I may also be able to get ones made up in mild steel from my template and/or template drawings subject to a suitable deposit

I don't really want to go down the 16" wheel route. Trackday car and tyres are going to be a fair bit more expensive. With the brackets, do you have to offset the bracket/caliper or do they not have to be notched?

depending on what size / type of tyre you're using... i found toyo proxes in 215/40/16 to be pretty cheap. only about £5 more than a 205/50/15

[MarkT]

I'm probably going to run toyo R888's. Where did you get your proxes from. I suppose I could run it on Vauxhall steel 16" wheels?

[gareth]

or some aftemarket tasteless alloys?

i usually get them from wither one of these places. the prices vary betweent the two but both are very cheap

The steelies should be a fair bit lighter.

Cheers for the links

Hi all,

this is my upgrade: fit under 15" rim

Front 300x25mm with Porsche/Brembo caliper


Rear 294x19mm with Porsche/Brembo Caliper

Hi,

What discs are you using?

There are seriously impressive brake upgrades in this thread! many future ideas......

If anyone is interested;

The setup I am using for 16's is a 296mm Alpina rotor with E36 328i calipers fitted with mounted with custom dog bones.

Two things I like about this setup;
1) I do not have to modify the hub as the rotors are designed for an E30, yet they are very big, and
2) I only need to buy generic pads to fit an E36 328i.

What I do not like about them;
1) They were very expensive (in particular the Alpina rotors at about AU$1500 for the pair),
2) I have to shave 1mm of material of each pad so that they fit (the rotors are 2mm thinker than the E36 328i rotor).
3) They are very heavy.

The fact that they are a single pot caliper does not bother me, because it is functional piston surface area that gives you braking ability, not how many pistons. That being said, if you can spread the pressure area out more (i.e. with more pistons), then your braking efficency is better again.

If I was to upgrade E30 brakes again, then I probably wouldn't use the Alpina rotors and E36 calipers as I have seen better options on the internet since, however at the time I was limited to this, or standard size rotors. However, with the Performance Friction PF06 pads I am using, the braking power is awesome compared to the orginal E30 setup (albiet fitted with bigger BMC, racing pads and slotted rotors).

The rotors are 296x25mm Alpina's with E36 328i single piston calipers. The pictures below show the difference in size between the standard diameter E30 rotor (DBA slotted) and the Alpina rotors. The fabricated dogbone is also shown fitted to the car.

Pretty cool - I like the ducts!

I made reproduction Alpina discs a while back (matching dimensions but a fraction of the cost)......but no-one wanted them so I let them go for peanuts! (I won't point out what I could have supplied for the cost of your Genuine Alpina discs alone as that would just be mean of me).

The latest 298.5x24 WMS kit's discs are a good bet for anyone messing about with kits this size as they are really tight to the balljoint, so just like the 280x22 G60 disc you get to move your caliper as far from the wheel as possible.

[MillRat]

Once these rotors wear out (12-24 months), I might come knocking on your door for some ideas.

The catagory the car is being built for allows free modifications on brakes, so BIGGER is better.

You are not wrong about what I could buy for the price of the rotors now.

You mean LIGHTER is better!

Pure race car I assume? By that time we should have more toys available for the E30...

Yep pure racecar, and yep I did mean lighter and BIGGER

What size wheels? I just managed to get 323x32mm rotors on bells / bigger WMS T35 4 pot calipers inside a 16" alloy.....juuuuuust.... (TVR not E30 sadly)

Here's some of my latest upgrade,just to show another option(have since sold the 4 pot Brembo setup)






Wilwood 6 pots with 335x32's and an E30 M3 master cylinder.

Seems to stop the car quite well for now

Further upgrades in the pipeline

Hi,

What discs are you using?

Cheers

The discs are special made for me. Front is from VW, Audi, Skoda Seat and rear E36 328. But no stock discs! The discs came out of production before bolt plattern and center hole is made.

I have the WMS 280mm kit on my track car and its much better than the standard stuff, even with a crap servo! The benefit is it goes under 15 inch BBS wheels and is half the weight



Just finished the front brakes on my road car, this is more for how it looks rather than performance

Audi TT 312mm disks and 540i calipers





Just the rears to do now, will be using a 294mm E46 disc and 540 rear calipers most likely.
Here is a mock up with the disks and E46 calipers

[321gazza]

hi badDave,like the 6 pot wilwoods,alloy bell set up, would fancey that on my e30 turbo.how much would that set me back or is it a custom setup.

hi badDave,like the 6 pot wilwoods,alloy bell set up, would fancey that on my e30 turbo.how much would that set me back or is it a custom setup.

It's a bespoke setup using parts I've sourced over a period of time


If you were to go and buy all new parts you'd be looking at roughly

£500-£550 for the calipers
£375-£450 for the disks
£80-£200 for a set of decent pads
£350-£450 for the mounting bells and caliper brackets
And another £30-£40 for all the nuts/bolts/washers

Not taking into account the new brake lines and decent brake fluid


I'd factor in circa £1500 ish for all new parts

Or £550-£600 ish if,like me, you're selective,lucky and find decent 2nd user parts on the cheap

[321gazza]

had wilwoods on my opel manta gte and like them alot,apart from pad rattle even with the bridge bolts,awsome brakes thou,wander if wilwood do brake kits for the e30.

billgatese30 has a 310mm Rally Design/Wilwood setup on his track car/weekend toy.

[billgatese30]

wilwood do a 280mm kit which apparently fits under 15"BBS (don't quote me on that though) and they also do a 310mm kit which fits under 16" hartges (and other 16" wheels probably)

TBH

I'd try and find a pr of Wilwood Superlites or some CP5200 from AP and get some 310x32mm wilwood disks and non machined mounting bells and make a 1/2 decent kit up myself.

That's pretty much the setup thats eventually going on the rear of my Touring,once I've sorted out the caliper brackets and get them anodised.
