Re: Upgrading classic brakes

To what extent are ya after upgrading Andy,can be anything from just std size discs with better pads/grooved std size discs+better pads/changing to 4pot callipers for the front with later std uk turbo discs.


Even going for bigger discs totally using the 4pots with a spacer bracket.

Depends what youre after mate.


"Think" an this is off top of me head rear discs are 266mm diameter on all classic turbos only difference being early ones "may" have been solid not vented.


Fronts upto 98 were 277mm/98-2000 with the 4pots were 295mm diameter.

Re: Upgrading classic brakes

JDM discs for a '97 WRX are;

Front - 294 mm
Rear - 266 mm (STi - 290 mm)

Would imagine the UK cars to be the same.

Be carefull with the drilled occasionally ive seen them crack between the holes-grooved alone would be fine.

Re: Upgrading classic brakes

Id go exactly with what Dave said above the heat from the disc can eventually crack drilled discs cause of the weakness of the hole Id go with grooved to

Re: Upgrading classic brakes

I was told by the guy I get brakes from that the fronts on a JDM are 294mm and the UK are 277mm. Also that the JDM version brakes run on a higher pressure than UK versions, and not to get drilled discs and to consider yellow stuff or equivalent rather than the red stuff usual. May be of no help but heh!

Sizes = Front 277 mm
Rear 266 mm Solid

Buy standard cheap discs and good quality pads (Ferodo) EBC waste of money on your model and red stuff bad bite from cold and dusty as hell, but work well on track..., fit new braided brake hoses, ensure your brake fluid has been changed at recomended intervals, if not flush out and fill system with new...

If this does not improve your brakes... then my brother is a monkey!

And dont forget they will take about 200 miles to bed in fully

If you want to spend time and money, replace your two pot calipers with four pots and get grooved discs...

Heres a link to Camskill and cheap discs Subaru Impreza Turbo Parts, Tuning, Spares & Accessories :: 2.0i Turbo GC8/GF8 94 TO 00 UK - Braking - Brake Discs ::

Good luck
