Caliper piston size and pad combination?

[Usr117063]

If all seems to work out with the rear mk3 setup, I have the option of non sport or 197 calipers, 34mm and 38mm bore size respectively, non sport being cheap as chips..

Im running 197 master cylinder and brembos up front with ds1.11 with ABS. Im not sure how much all this will make a difference to the braking system but I want it to be balanced at least. Im looking at ds1.11 or pagid rs4-2 as carbone lorraine and winmax are next step up in budget.

Im not sure how the abs works completely but my thinking is that I dont want the rears to be too aggressive and firing up too easily so the 34mm with race pad is the better option?

Any help appreciated

Bigger piston doesn't necessarily mean more pressure or force. It's just more even pad contact.

But seeing as standard 1*2 rear calipers have tiny pistons, I think the 34mm will be fine.

Whats made you want to go with MK3 calipers on the rear @ZachB ?

@YorkshireKyle The recent incident with the rear stub bolts all snapping I want to be (feel) safer as I think the mk3 setup is a better design and stronger, heavier car after all

The mk3 stub axle is internally threaded so get bolted to the beam rather than a nut and bolt through.

Sounds like an upgrade I may partake in them because the stubs on mine are put on with bolts that I'm not particularly confident in!

Just make sure you refurb the calipers as they're a massive c**t on the MK3 platform mate... Don't ask me how I know 😂

lol thanks for the heads up! Yup 10 quid each for seals will see how pistons are when they arrive

If you've gone for non sport then they're a bit better. The 197/200/R26 ones seems to just let crap in and stick on!

Yeah, money making scheme so you have to buy new calipers every year😂
