Lexus is300 diff swap M98 3.91 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

My 86 is boosted (420whp) and 305ft lbs torque. I've been thinking of changing the diff to the is300 which is a straight bolt on. Anyone out there with a boosted 86 do this swap and how do you like it?

What are your mods, and impressions?

Where did you source it?

Thanks

I got it from a junk yard with 45k on it. im super charged and use the car mostly for autocross so i really like having the higher top speed in second gear. the power differently makes up for the little lack of acceleration.
