Hi, I'm a college student living off of grants and scholarships, so I'm not loaded. I want to do a brake upgrade, but i'm not sure as to what route to follow. I was thinking about getting Project Mu SCR rotors, Project Mu B-Force pads, Project Mu lines and here's the tricky part... my friend recommended I do a Supra TT caliper upgrade. Is this wise? affordable? do-able?? I'm open to suggestions- actually in need of suggestions. BTW... I'm running on about a $1500 budget since I'm using the rest of my money to get a set of TEIN Super Street coilovers and EDFC system. (if you recommend a better susp syst, please speak up before I buy) THNX!

you seem all over...I'd assess what you don't like about the GS first.
randomly putting on parts is an option though.

lol well I'm still a young student of the tuning world. Being honest I want to have a show-off quality car, but before anything I want it to perform good. I know the GS is not much of a track car, but I like to have fun with it. I live in central PA and there are a lot of mountain roads around with beautiful turns that I like to hit up when I'm bored (almost daily), so that's why I need better and faster braking. As for the suspension, I definitely want a better set up to handle all this weight around the turns. I figured the super street would be a good set to start with. I hope this gives you a better idea of what I seek...

The cheapest way is puttin LS (Celsior 20) front brakes. But there is some problem with putting R16 wheels after.

like i said, you are all over...and super street is probably not the best start.

read past threads, look at people's cars, and drive the living **** out of the GS. Figure out what you don't like and upgrade from there. Toyota spent a lot of time engineering the GS. Us messing with it and putting on some blingy super-street-advertisement parts is not going to do it.
i mean, why brakes? pedal feel? initial pedal feel? fade? noise? all elements that make up a 'brake' is there and chosen for a reason. what's wrong with the stock suspension? height? if you haven't read about all of us having a headache over the lowered GS with, try reading those.

PS: well?

and how do you plan on clearing the tie rods?

and also, bigger caliper = bigger stopping power?

if you want pure stopping power and minimize stopping distance, ditch that integrated ABS/booster unit and swap a JZA80 unit or something.

I suggest you SEARCH. You are going to mod a Lex on a $3.95 a week allowance?

He will need to modify a little bit. And also wheel should at least +38ET. The main advantage of LS brake caliper has 4 pistons (ours 2)
Looks like this:

So I looked around other threads and did a huge amount of research on the LS400 brake upgrades and compared it to the supra TT brakes. I like the LS kit better, and I realize the issue with the spacing so I've looked into an RCA set up and it seems pretty do-able.

A problem that I'm having is that I believe I have to replace the Master Cylinder because I think the one in my car is done. When I hit the brakes even just a bit harder than usual, the brakes kind of get stuck (like if something was blocking the pedal from behind) and I could feel movement through the pedal like if it was trying to latch on to a gear or something (it's only an example I know that's not the case). at first I wondered if it was air in the lines, but I'm pretty sure that's not the case. The worst part is that when I do hit the brakes a little hard, even if I'm going slow, it gets stuck but the car doesn't really stop, it keeps going until I let go and then pump the brake again. Has this happened to anyone? and does anyone know where I could find a master cylinder for a 2GS3 for under a grand, in case this is the problem??

i would check the calipers first, make sure they are not semi frozen. Make sure you are not leaking fluid. check your pad thickness. I noticed with mine that somehow the system did not like a low pad, as in any car this will give you a low pedal, and in the GS, My experience has been that it creates the double pump condition.

as soon as i replaced my pads and Lines, lubed the caliper pistons/pressed/depressed, it went away.

The ABS is what goes in pre 2000 MC units

Almost forgot, If fluid hasn't been flushed in a while (a year) it can also affect the pedal feel, it will not feel as firm and may give the low pedal no pressure feel causing you to double pump.

I had Tein Super Street coils when i had my gs and loved them. BC Racing makes a comparable coilover system and its cheaper. Along with the LS caliper swap, make to get stainless steel braided brake lines and flush your fluid. Also, your stock 16s off the early gen gs will not clear the calipers without spacers.

Mrpoop87

Cool yea I'll check for all that... once it finally stops snowing here in central PA. question though, how can I check to see if they are semi-frozen? what do I look for?

Mrpoop87

That's good to know about the Tein's. But after a few days of staying up till 4am looking through threads, researching, and comparing, I ended up going with Megan LP series coilovers. I chose these because of the amount of adjusting I can do to them compared to others, and because the feed back on these seemed to fit the description of what I was really looking for. I ordered them already and now I'm trying to find an RCA set to make way for the brake upgrade. as for my wheels, I have 18's. Would these clear the caliper? or do you think I'll still need like 10mm spacers?

i drive my car same way sometimes ...the feel u get in the pedal is the abs working for u in order not to lock up any wheels (a little bit of a prehistoric VSC system but it works)

the feel u get is because u stab the brakes and for a second it feels like its not braking but as soon as the calculations are made by the computer it starts to brake just fine.

Also u can not just go in there and change the master cylinder...the GS has a system of all in one and is not ur typical booster its actually a nitrogen tank and a compressor.....do more research

back when i was at university i spend most of my government money on my TT 300zx (about 10k ) now that i look back and think about it maybe i should have done something better with my money like travel or save it for a rainy day but till this day ...the car bug is still here and spend every extra cash i have on my cars ....
