I reckon that depends on what you want your car to do different ...... :popcorn:

How do you use your car and is it manual or auto?

I daily drive an its manual looking for some more bottom end in it

More bottom end .. if NA, in addition to FD upgrade i'd look also into Crawford BPBs. They move main torque/powerband in lower rpm-s ..

Ive have seen them do they work as described on the website

Here's my thread on FD swaps, I used the 4.56 FD swap from weir performance and I believe it's less expensive than the mfactory. The main thing is to find a reputable shop to do it for you honestly

I've had 3 different final drive setups in my car. 2 rules that I follow are:
1 Only let a qualified shop do the install, it's not for the beginner mechanic don't skimp on this or you will have a noisy or short lived diff.
2 Use a quality fluid in your diff.
The only 2 shops I trust to setup my diff are Spencer Fabrication in NH and Weir performance in CA I have had flawless work done from both companies. Both offer the same parts and options. DO THE UPGRADES IF YOU DRIVE HARD!!!!!


A 4:56 ratio would be the way to go with a manual daily driver

Did it help out alot with bottom end power

Is it on there website? They only list supra stuff on there or celica stuff

I didn't see it either I guess I'll have to call.

My assumption was that you needed a M98 or M85 diff to swap in the correct gears turns out you dont need to do that anymore?

The FD's for the FRS are not listed on their website, but spence does respond fairly quickly to emails.

You've never needed to do the swap in a separate diff. People were doing that so they would minimize downtime of the car being in the shop. If you're in the Pacific NW VIP performance did the install in 3 hours with no whine from incorrect backlash etc.

Buy weir gears, it should be the mk3 supra gears, but when you call him he'll know which works. It'll be far cheaper than mfactory or cusco.

Huge difference in usable torque accross the board. Keep in mind that it will not change the torque curve other than raise everything by 10% in torque applied to the wheels.
I would suggest to get a catless header+tune to get rid of the torque dip then get the FD swap for the extra low end :)
Sorry for the paragraph, but people keep asking questions lol

Night and day difference in my opinion. A lot more power on the street. ran a 1.82 60ft

Supra gears get the updated bearings and solid sleeve

Higher FD does wonders to increase the cars "eagerness" it wants to get up and go, this is apparent even at parking lot speeds. I have gone lower for my turbo car and while pulls are better now, I really really miss that low speed eagerness it used to have even with just a 4.44

Save your money and spend it on UELs
