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.
 
 
 

yeah it's mostly a daily driver, few twisties here and there (esp to the snow). only been tracked once.
 
 

oh interesting: http://backfires.caranddriver.com/posts/837-brake-rotors-don-t-warp 
 

'93+ brakes and M/C FTW! ;)

I know... I'm trying to save money, not spend it.  but I'm starting to think my calipers may need a reco... or something...
 
I dunno asside from installing brakes I dun know very much about diagnosing issues :p

^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.

yeah - atm I'm using wilwood calipers + pads... ;)
 
there seems to be a lot of kinds of brakes... which RDA model number am I after for my car...?
