Ya guys think having the rears make a big difference as opposed to have just the fronts?

gadgetSC

Yes there is a noticable difference.
I first installed the fronts with new pads for the stock rear and noticed some instability with sudden braking. The car felt much more stable after installing the rear TT brakes. My 2yen

IF you can get front and rear you will love the brakes they work great .

The TT calipers are 2 pot, vs I pot for the stock SC calipers. So ,therefore, you should have a bit more rear braking power.

Are the TT rear rotors the same as SC, or are they larger diameter than OEM SC?

vipsoarer

the rotors are bigger on the supra than that on the sc. you have to trim the dust cover on the sc to allow the rotors to fit properly.

Couldn't you use Supra TT dust covers?

Yes you can. There is a write up on the TT brake install on the Australian Lexus Soarer Club website. In the write up, the installer puts on TT dust shields. I priced then recently and they are not too expensive, less than $30 per. However, just as in the removal of the stock dust shields you have to do some trimming to avoid having to pull the hub, you will have to trim the TT shields to install them. However, they will bolt up just fine, according to the Aussie site. Check it out, their tech write ups are very thorough.

alrighty... i guess my next question would be... how much did you guys pay for front AND rear?

BLK13X

Are MkIV Series 2 brakes easy to find in the US (say, of wrecks etc.)? They seem to be a bit hard to find here in Australia, the 4 pot fronts and 2 pot rears (I think they were 2 pot rears)?

Hermosa

I actually put my rear calipers on first before the fronts and it was weird being pulled to a stop by the rear brakes.

Hermosa

Supra rears are 1pot not 2. The rears are 12.6" like the fronts.

so how much did ya guys pay for your TT brakes front and rear (or seperately)?

rushgator

Hermosa, the info I found on the Supra TT calipers says they are 2 pot. However, thr info is from the Aussie site, so it may be different there. I have never seen a Supra TT rear caliper (execpt on a Supra) so I can't say for sure. You may have seen several, so you are probably right. Now I'm curious: is there a 2 pot available, or are the Aussies wrong on that? Here's a part of the article: (it didn't space very well, but you can figure it out. Or, you can go here: http://www.lexus.australia.as/entry.htm and see for yourself)

ummagawd : These prices are Ausssie $'s, so you will have to do the conversion to get the USD price, but I think it is a fair comparison of what you should expect to pay.

TBA??? (To Be Announced??)

Forgive me for not knowing all the chassis codes, I would suppose the UZ is equivalent ot the USDM SC400, as it has the 1UZ engine.....

From the FAQ on intellexual.net
So the sc400 brakes might be somewhat of an upgrade for the sc3, but NOT as beefy as the TT upgrade.

I'm not advocating the sc400 swap over the TT, just adding it for completness I suppose.
