There's another way, but I'm not telling either !
nah, the ls430 calipers they won't fit at all (the holes don't match up), so the new brackets were more than just rotating it to 12 oclock

OK just saw that jtanoyo1 was talking 430, I was talking about rotating the 400 brakes in order to clear the steering. Actually in both cases, we're talking a custom bracket that needs to offset the calipers from the stock hole spacing to a new location.

Yes, these DSR brackets would make the LS430 calipers a plug&play affair.

So LS 400's are smaller than Supra TT....shesh...that should make for easy install, but I guess there is some kind of trick to it ?


I can't wait to hear more info on this

Henry, the rotors on the 98 - 00 LS (which is what I think are pictured here) are a little smaller than those on the Supra TT setup - maybe two tenths of an inch. There's an old post somewhere I read comparing the two, but I can't seem to find it right now.

It's not fair you have access to all those goodies, Jtanoyo...unless of course you are willing to place some orders for your less fortunate brothers .

I am curious to know if the LS brakes offer more stopping power than those from a Twin Turbo Supra. I currently have the TT Supra brakes on my car but if the LS brakes are better, I would switch to them in a heartbeat (no matter how much cutting I would have to do IF Jtanoyo won't get me the brackets...LOL). Also, when it comes to caliper clearance for the wheels, are the LS brakes as much an issue as the supra brakes or would just about any 18 or 19x8.5 fit over them? My choice in rims is currently severely limited because of the supra brakes. Love the stopping power, hate the clearance issues.

Jon-

Is that bracket aluminum? 6061 or such?

yeah that's correct, actually i talked to jawnthen, and he said he put the caliper on a supra rotor, it cleared but couldn't turn, so that's how close it was

somehow i interpreted it as alredxiii was saying the ls400 claiper is smaller than the supra tt, that's why i asked why

sorry about that

The LS rotor is only slightly smaller than the TT.

I did do a comparison of the TT vs the LS , but I don't have all my notes with me right now.

Rougly what I know:
1. Rotor diameter on LS slightly smaller. Probably insignificant performance wise.
2. Both are 4 piston, but need to verify if the diameters are the same.
3. Pads are different shape and one may have more surface area than another = higher coeffcient of friction.
4. The LS has slightly more wheel clearance than the TT, but again I don't know by how much, just that it's better.
5. The biggest difference is that the TT calipers are steel and the LS are aluminum. The difference in weight was roughly 5 to 7 lbs. each.

So that's a general comparison. I plan to publish a bunch of brake comparisons in the future, so you'll have to wait a bit to see more detail than what I have here.

Default LS400 brakes do fit 2nd Gen GS!!

LS400 brakes do fit on 2 Gen GS with a lil custom made "Thingy"

Who would be interested in having LS400 brakes on their GS? The whole kit would be somewhat cheaper than Supra TT brakes. After all, that's why most of the SC's out there run the LS400 brakes, because they're cheaper than TT and they work almost as well.

The Supra brake pads are slightly bigger than the LS400 or LS430 calipers, but this does not mean that the braking power of the LS is less than the Supra (or more ...).
In fact the GS pads are even longer.

Other factors, like rotor size and piston area are also important....

QUOTE]

Each factor: rotor dia., piston dia., pad area, piston count, pad material, rotor design all factor in to braking performance.

My thoughts are that more brake pad surface area in contact with the rotor = more contact patch = better performance.

The GS may have a larger pad,which is offset by smaller rotor, 2 piston , etc.

Nice pics of the pad design.
