Hey all! So I'm in a situation. I've been sitting on some 4 piston Supra TT Brake Calipers and OEM Pads that I scored from a previous CL member and have a few questions. I've pretty unintelligent when it comes to brakes and specifics on the subject. Any help is greatly appreciated.

1) I know I will need new front rotors for these to fit on my 2002 SC430 (including trimming the rotor shield). Can anyone recommend what model of rotor, or even which stock vehicle I should pull the rotor from (year, make, model, please). I would prefer drilled and cross slotted to match my rears. Any suggestions, please?

2) As some of you know, I have two sets of 20" rims (winter and summer). I want to make sure the calipers will clear both sets. I've listed the details below for each set. Please let me know if you think the calipers will have enough clearance.

Summer- Roderick RW2 Cinque Black/Machine Chrome Stainless Steel Lip (5x114.3)
F: 245/35/20x8.5+35 CB66.6 Backspace: 5.63
R: 275/30/20X10+38 CB66.6 Backspace: 6.15

Winter- U2 55S-A Chome 5 Spoke (5x115)
F: 225/35/20x8.5+13 CB73.1 Backspace: 4.75
R: 245/35/20x8.5+13 CB73.1 Backspace: 4.75

Thanks in advance for any opinions and advice.

Hi!
Yes supra tt brake calipers will fit, i got same.
1) My choice is DBA HD series rotors.
2) I know that the distance from the working surface of the rotor to the edge of the caliper 55mm

The only real way you will know that it will fit is to try it. My rims touched at the outside corner of the brake caliper, that is why I added spacers. Somewhere in a thread there is the actual model number of the brake rotor that I bought. I will look for the link.

Anyway, I would pull off the stock caliper and tie it back out of the way - without disconnecting the line, drop on the new rotor and caliper, bolt it up and throw your tires on.

I forget are you in Chi-town or in OK now? Anyway, I was going to offer if you want to bring an extra wheel with you, you can swap it on my car to see if both fit if you blow through Kansas City.

Thanks for the advice. I will look at those rotors specifically and read up on that entire thread when I have time. I'm currently in Chicago and will be doing a tire swap really soon so I will test fit the calipers and touch up paint my current ones while I have The Lex up in the air. I do wish I was in KC though to see if they fit and clear on your car.. Might make a roadtrip in late down down to Oklahoma to visit the folks. Will surely have to meet up then but I hope to have this work done before then.. but worst case scenario will test fit then. Thanks!

Checked out the 128.44104R and 128.44103L by StopTech and unfortunately they are only cross drilled. I would like to find a set that is cross drilled and slotted to match my rear Kinetic rotors. Any other suggestions on reputable brand of front rotors? Kinetic/PowerStop don't make matching ones for a 1997 Toyota Supra. I have the OEM Toyota Supra Pads already. Thanks for any advice.

Shawn, I have those cross drilled stoptech ones.. They are GREAT! and I don't think itll be a big deal with slots in back.. but I know its nice to match!

how old are your rear rotors? perhaps if they need changing soon you should by a package together..

All my rotors are only little over a year old now. I did a swap when I bought new 20" Roderick Rims. I thought about a package but from my understanding the rear supra rotors won't fit the SC430, so I should only purchase the front.

Hey all, I know its late so I hope someone with the upgraded rotors and supra TT calipers will read this early as I'm going to my mechanic tomorrow to test fit on the OEM rotors to judge figment on both my wheels. I would like to know the demensions (diameter, radius, etc) on the larger front rotors. I really hope someone will help me out in the morning. Thanks to anyone willing to help!

Additionally, I was told that the front rotors from an LS400 might also fit with the Supra TT calipers on the SC430. Can anyone verify this, and if so what year LS400? Thanks

I believe the Supra rotors are bigger than LS400 rotors, not by much maybe less than 1" diameter. You want to get the right rotors to have the right fit with the calipers.
Just for your information, the LS400 rotors will be from 95' to 99'.

Thanks for the advice. I did test fit this weekend and they will bit both my rim sets, so hooray! Now I need some help on choosing the proper brake lines. I don't know which ones are proper and I'd like to go with stainless. I'd also probably like to change the rear to stainless to match. Can anyone suggest the proper ones in stainless for front and rear, please?

I bought Stoptech stainless steel brake line that fits LS400 front brake calipers, but I end up not using them since the OEM lines have a small "hook" that fits into the calipers to make a more secure fit. I think you can just buy the lines that fit SC430 and the lengths should be correct since the Toyota /Lexus all have the same thread on their brake lines.

Very glad to hear that they fit! Excited for you.

I think that I bought a set of lines for the Supra too. I did not go stainless.

So it seems I have a new problem. My mechanic helped me disassemble my calipers so I can paint them. Had to cut one of the caliper pins as it was stuck. New one is $5 at Toyota. No biggie. BUT my real issue is that my mechanic said I should get the pistons refurbished. He said there are certain shops of companies that can do it but he didn't know anyone. Does anyone have any suggestions? I really want to use these, but its truly becoming a challenge. Someone please give me so good news.
