so i ran the set up with and without the frs torsen LSD, man do i miss it and how strong it holds the ground around the loop. the problem i feel is that the rpms sit a bit high driving regularly. so i will locate a 06-XX is250 Manual trans, which have same final drive gearing. I will attempt to install the is250 final drive ring and pinion gear on the frs diff and reinstall it back on.

update on the torsen t2 limted slip on the gse3. drives completely like stock. no changes whatsoever. what i did was picked up a m85 is300 manual trans pumpkin, i cleaned it up and slap new seals on it. also a direct fit and works as it was intended. power transfer to the wheels move side to side to the wheel with the best grip. recap. i ditched the frs 4:1 ratio final drive for a m85 3:7 final drive. is it that big of a deal? maybe. but it helps.

That's why Lexus IS 250/350 don't have LSD Lexus Engineers thought of that ! i've been driven like an a-s-s lately these days to test out New Lexus IS350 suspension and AVS, had the car for awhile now in my opinion i would say Handling and grip is better than BMW 330ix i compared 2015 IS350 Fsport to a 2017 BMW 330ix, i thought 330ix suspension/handling were GOD, Fking same sh't, compare strut vs strut. Guess what i Spun out on track with 330ix. except the Suspension and steering wheel were little stiffer than Lexus in normal Mode but when i turn on SPORT+ on Lexus IS, i like it better the stiffness is just enough like me *****.
Lexus BMW Merc and Audi are Luxury performance, it's not worth to replace the parts with Aftermarket one, you guys are in delusion and imagination. oh i heard its good, oh i think or i feel my handling has improved, save money for Custom Turbo !

A performance-centric component like a LSD that can help apply power to the ground under inclement weather or enthusiast-driving conditions is a welcome addition, regardless if you're driving a RC-F, IS250/IS350 F-Sport, 1st Gen IS300, or a FRS/BRZ.

Do you always sputter nonsense when you type?

Show me where I state that I have a 204hp car.
Reading comprehension is a fundamental skill that's obviously not for everyone...

Frs diff swap into is 250
Hi! New user here and I’m planning on doing this same swap on my 250. I had one question before I started mines , when you removed the axel from the diff did you HAVE to loosen it from the hubs ? Or would it just drop out ? And also any advice on how to loosen the axel from the hub if needed ? Sorry I know this is random but this was the only good info I found on this swap and I was hoping you might be able to help haha
