1990 JDM Turbo stock brakes part numbers
Hey everyone.
Does anyone have suggestions for new pads and rotors for a 1990 JDM turbo mr2 including part numbers? Looking for best bang for buck.
I'm thinking trw pads and rda disks. I want disks that won't warp easily. The disks I had on the car originally warped, then the willwood setup I had seemed to have warped too!

Depends on what the main use is.
For a daily driver I found with my '90 model NA, genuine Toyota pads used with new RDA plain rotors gives great smooth braking, and I have the small early model brakes.
Been on now for about 20k and still no sign of steering wheel shake under heavy braking.
Got the pads from Lithia at about $80 US the full set F/R.

^If I was trying to save money I wouldn't own a turbo MR2, like someone once said you're forever chasing your tail doing maintenance :P
What braking 'symptoms' have you got?

steering wheel shudders like F**k under braking.
DIY maintenance isn't too bad actually:) I recently did some touring round vic in it, and got 440k per tank (doing the length of the GOR on boost too :P)
it's quite good actually.

If the steering wheel shudders under braking, it'll be from your (front) rotors being warped as you mentioned.
Just get a replacement set of front rotors (RDA or similar) and new pads and go from there. You also could try and get your current ones machined/skimmed if they're not too thin which would save some monay.

have a look at my thread i started a month or so ago.
i ended up just flushing and replacing the brake fluid . makes a difference for sure.
although if your shuddering on braking then somethings warped. time to replace whatever it is. RDA is the cheapest i think, look on ebay they have them listed for 89-91 i think, afaik thats the smaller brakes
i have TRW pads and they are good.
Should have come to the MR2 DIY day last month, could have done this under supervision and would have cost you $$ only in parts

yeah I read your thread. Just wanted to make sure I was getting the right sized rotors etc for my car. is there a difference between the NA and Turbo 89-91?
It's ok I know how to flush brakes / change them. just trying to avoid warping things again.... I installed the willwoods I have on the car currently myself without any dramas. I'll prob just get some TRW pads and RDA then. But on second thoughts, will have a look at the rotors, just in case it's a bolt that's come off (they're two piece rotors...)

What does the surface of your Willwood rotors look like (wear or grooving etc),
Maybe they could be resurfaced anyway.
I'm wondering how well did that front setup when you first fitted them? Slow deterioration over time?
Anyway, I assume you are thinking of going back to the stock front calipers as well.
Early brakes are the same for turbo and NA as shown below.
