Default Will 4 pots fit under standard 16” wheels originally 2 pot sliding callipers

Good evening all,

just a quick question but I have standard 16” wheels currently with 2 pot sliding style front callipers on my 97 type ra and have some 4 pots turning up this week.. are they likely to fit without the need for spacers?

cheers

Tom

Yes. Straight bolt on but you need the matching 290mm vented front discs.
I did the swap on my MY 97 WRX RA.

Thanks for your reply, I assume you mean the 295mm discs? Did you find they made a decent upgrade?

ANYTHING is a decent upgrade to the crappy calipers fitted for the UK market. They were a disgrace!

The short answer is v1 and v2 factory 16" wheels with two pot callipers will not fit over four piston callipers. Uk supplied speedline safaris will not fit either. All V3 jdm onward 16" will accommodate four pots. The four piston callipers are a big improvement on the two piston.
Post a picture of your wheels, might be able to give you a definate answer.

Sorry to jump on this but would four pots Subaru calipers fit on the rear of a 97 v3 STI?
Does the V3 STI have one pots at rear and two pot at front as standard?

Thanks all

Don't think anybody has tried?!

Being an STi, it would have the 'S U B A R U' 4-pots at the front (and not the rubbish non-STi floating 2-pots).

The rears are also a rubbish floating (single-pot?) design, I think.

The common upgrade for the rears is the Type R's 2-pots, with spacer brackets and their matching 290mm discs. I have this mod on my own 4-dr STi Version V.

I believe you can also fit the New Age Brembo gold rear 2-pots/discs, with suitable adaptors.



Thanks all

See in red ^^^

V3/MY97 RA, like I had, so the answer is still yes.

Get braided lines, good quality discs/pads and fluid and the difference is great.

I want to upgrade front and rear in time properly for sprinting and get involved in the white line 22 series but still training on my job at the moment so that’s a few months away. Thanks for all of your replies and info, much appreciated.Tom

Ah, yeah, the RA is the car you'd buy for competition use and alter it - hence RA for Race Altered. That's why they deliberately don't have any fancy bits on (aside from the DCCD of course), as you'd throw away and modify most of the OE stuff - brakes included.

But then you know all that, already.

No DCCD on a WRX RA.

I was talking specifically about scoobydreamer's car. Which is a WRX Type RA STi.

But I can see now that my post actually reads as if I'm talking about all Type RAs, in general. So apologies for any misunderstanding.

The wheels in the picture are speedline st2 I had these on my own ra with four pots, no clearance issues, straight swap. Twin piston callipers clear the rear wheels too.
