2000 gt front disk to 2001+ spec conversion

[CooBlueDAB]

For record... I do autocross. Which is why stock may be bad with fade.

Just like it sounds. I just ordered the parts needed to do the swap to rear disk on this thing, basically because of part availability. then realized that the rear brakes are going to be bigger than the front, and the aftermarket for 2000gt front brakes are less than the rear drums.....

What is needed, to do the conversion from a 2000gt FRONT brake set up to the 2001+ gt/gts? Is it a hub thing like the rear? and if so, can I reuse the same calipers but a different mount? or is it all done for?

***OPTION 2... cancel my order... keep front disk, and rear drum... And take your advices on pads/disks/shoes for the stock set up.***


Thank you in advance.



So far I was thinking in this setup/pattern.

2000 celica gt front brakes same as
2000-5 mr2 spyder brakes

----PADS
front
HB493F.650 hawk hps as per Hawk $70.44 pro street online

rear for 2003 gts
HB329F.543 hawk hps as per hawk $72.29 pro street online

----Disks Brembo
Front 25645 2000 mr2 spyder
Rear 25565 2003 gts

----Disks r1 concepts
Front 120.44119 2000 mr2 $87.89 blank for pair of 2
Rear 120.44115 2003 gts $56 blank for pair of 2

No one has any ideas or advice? Could I at least get some opinions on brake bias? I have heard from people that it will be uneven with 2003 rotors on rear and 2000 stock gt brakes front... if it does not matter, Ill go for it, but if it matters, I'm going to keep drums and resell this 2003 gts rear brake setup.

i really did not think that rears were ever larger then fronts. even if the rotor is similar size, the piston and pads on the front are larger then the rear. i think its 70-30 or 80-20 ratio. I also don't recall anyone complaining about it. also all of those companies make the rotors specifically for the celica so i would stick with them as opposed to going the mr2 rout. If you are looking at other cars, the TC has the same front brakes as us but i cant confirm the spyder does or does not

yeah, tc does for 2001 gt on, but Ive got a 2000 gt, the single only one with it lol.. smaller rotors and pads than every other model and year. as for MR2, I confirmed part numbers were the exact same... that is the only reason I said that. lots list mr2, but not a lot list the 2000gt. for pads etc... but if stock are same, then aftermarket same.

Spyders are having 4x100 wheels so you definately can't fit those rotors to your Celica.

I don't recognize those part numbers...what pads are they? HP+ or HPS? etc...

You can run something like the HP+ up front, and something less aggressive in the rear. I have no experience with how well the 2000 GT brakes work so I can't give you an educated opinion. The HPS in the rear might work well...or you may even want to stick with the OEM ceramics in the rear. They're pretty good actually...the only reason I ever upgraded pads was for the real track. I've autocrossed in 100+ F ambient temps and never once experienced fade on OEM pads. '01 GT, so drums in the rear and the fronts doing all the work.

Don't know anything about converting. I would assume if you bought all the correct parts (rotor, caliper, caliper mounting bracket, etc.) it would bolt right up.

The other thing to consider, however, is classing. Not sure what class you're currently in. If you change from drums to rotors, or use a rotor that is larger than OEM, at a minimum you get thrown into STX. Not the greatest place to play for the Celica, you'll be taking on WRXs and E36 M3s.

If it were my car, I'd keep the brakes stock and wait for next year when the Mini Cooper S gets moved out of G Stock. The latest gen Civic Si will probably be the "it" car for the class but the Celica should still be fairly competitive, probably more so than anywhere else. I've done well against the ones that show up locally...how much talent is behind the wheel, I can't say though. Save your money for spare wheels and a set of Hoosiers. ;)

I have the most experience with HPS pads. and be these pads stock or cheaper replacements, they are done after a stop from 60 and one from 30... cooldown needed.

I ended up finding the info, I can just use the mounts and calipers, as for classing, being stock parts for a body etc... I might just be able to call it a GTS. but I usually do autocross or track events with the club, it is moreso for myself rather than national. So I am not too worried
But I have always compared myself to the top tier drivers. which have been the RX8 driven by a goodyear test driver, WRX Sti by a retired racer, and some Porsche Carreras by the vets of the club. I was doing this in a 99 civic si, with all stock except for an upgraded clutch and flywheel, as suggested by the group to help with wear, with over 140k miles on the engine lol. Then it was stolen, so here I am with a celica, the car Ive wanted for years, aside from an STI. Regardless if I can stay within 5 seconds of the 1st place car as I generally was, I'll be as happy as can be. But I think I'll do better comparably. the turn in is much better and understeer less as turn goes on if I need extra speed off the turn. I also seem to have better power in second gear for the speeds the tracks usually run at. 45-65mph But we always have a LOT of near stop turns. a smooth slalom has always been my friend in making up seconds over the more powerful cars.

Very strange. It took at least four laps on a road course for my OEMs to start giving up the ghost. It was the first session so we had a speed limit...each lap had two braking zones from 80 and one from 75. Over 100 degress F that day. This is with an automatic tranny too, with terrible engine braking that requires more work from the real brakes.

I think you'll be very satisfied with your new brakes though. ;)

without a doubt. I love the hps's aside from the extra dust, but whatever lol. I know the front rotors are slightly warped but I doubt that is why they gave out. I'm fairly certain whomever was ahead of me, used the cheapest pads/rotors around. I am also the unlucky soul to have a gt, from before 2002, with oil burn. but new engine will come with time. hooray for free top offs at Valvoline.
