I have a 90 RS with a 3.1 EFI

The parts store sold me set 3 & set 6.

Set 3 is for the outer bearing with a 1LE brake option.

I think the outer bearing should be a set 34 which is for a non 1LE brake option.

I don't even know what a 1LE brake option is & I haven't test the bearing in the rotor for fit.

1LE is a rare performance option with larger brakes. You would have 1LE in your RPO codes sheet if you had it. I had trouble with the store not being able to tell which bearings were for 1LE and non 1LE. Here is a link to my thread. https://www.thirdgen.org/forums/susp...out-wheel.html

Thanks!
