You got the GT rotors; they're vented and slotted, but not cross-drilled. They should handle higher temps and heavier pressure better than the SRP rotors. I ordered the same kit you did with the four-pot forged Superlites but since my tC's a daily driven street car I went with the SRPs (cross-drilled instead of slotted). I ordered my front kit along with Wilwood braided steel lines from Precision Brakes Company and it should be arriving in a couple weeks!

Now, I do know that the limit to my car's braking ability is the tires and not the brakes, but I just haven't been fully satisfied with the brake feel and modulation on my car; I feel as though I'm having to press the pedal farther than I like to get the amount of pressure I want a lot of the time, so I'm hoping the braided lines, if not the larger diameter rotors will help that quite a bit (in a way, I prefer quicker brakes/less pedal travel for more brake force, or should I say, more sensitive/more difficult to modulate, as I am confident in my ability to modulate precisely even with quicker brakes).

It would seem to me that simple physics dictate that by using a larger diameter brake rotor, less pressure from the caliper is necessary (given the same exact pad, but then again I'm changing pads too, obviously) to apply the same brake force. Yes, I do know that by cutting down on pedal travel for the same brake force, I am cutting down on modulation precision and simply making it easier to lock up the brakes/cause ABS to fire, but it's really a subjective/preference thing--I actually want tighter brakes and I am perfectly confident that I can handle them as such.

Please feel free to correct me on that, anyone, as I'm just going by pure theory and jest--I have no hard data to back up my own conjecture. I am certainly not going to lie about one thing though--I really like the looks of this kit compared to even the stock pieces with painted calipers (why else would I go with SRP over GT?).

Wilwood doesn't make a rear kit for our car, so I am having Precision Brakes fab me a custom rear kit; 12.9" SRP rotors and four-pot forged Dynalite along with Wilwood lines. The custom fab job will take them four to five weeks longer.

I can't wait to get them in!!! Precision brakes is doing free powder coating this month (red, white, blue or yellow) but I decided to stick with the stock black w/white lettering from Wilwood--I felt it would go nice with my SSM tC, and it seems that everyone else has red (except Rick, of course), so why not try something different?

Say, Rick--do you think these brakes will fit the stock 17" wheels that come with our car, or should I decide seriously on something 18"? I really like the look of the stock 17" wheels (other than the fact they're six-spoke wheels that attach with five lugs), and have been extremely hesitant in buying 18" wheels & tires unless the brakes really don't fit. I've been looking at a bunch of options (the Enkeis that Toyota sells, Axis Reverbs, Axis Hiros, Axis Decades, BBS CVs, Kazera KZ-As, Gram Lights 57Cs) but haven't really settled on any since I'm really hoping to keep the stock ones (I got lucky and received the Yokohama S32As with my car, rather than those dreaded Bridgestone RE92s). Precision Brakes has not yet sent me the templates for test fit. Haven't decided on 18x7.5 or 18.8, but I think that decision comes more with exactly which wheel I settle on.

As for tires on the 18s, I'm almost completely settled on P-Zero Nero M+S. New York snow is a genuine concern to me, and I'm far too lazy to swap out three-seasons tires for Blizzaks. Living in an apartment with minimal storage space, I'd also have no idea where to keep my spare wheels & tires during their off season.

(Welcome to the site)
Thanks!

I promise not to make such long posts...

...all the time, at least (sorry, it's a habit of mine).

Make them as long as you want!
Don't know about that...I actually moderate a different forum (SilentPCReview, anybody here know of us?
) and have made some insanely huge posts in there--even whole threads made up of insanely long posts!

But then again, those posts were filled with not just text but temperature data, power data, subjective noise notes, benchmark results, photos and other stuff...

PS Speaking of that, I better just get back on topic...

Hmm, if it's an issue of the calipers running too close to the back of the spokes, I would think going for wheels with an even tighter offset, no matter what diameter they are, would actually be detrimental, no?

Here's another query for you: Let's say we have a wheel offered in multiple offsets; which one mounts the wheel farther in (i.e. closer to the caliper), +35, or +45? From what I've read, the stock 17" wheels are +45mm offset, so if I have a brake clearance problem, I need to know whether to go downward in offset (+35mm, for example) or to go upward/use a spacer (I haven't really seen many wheels in 18x7.5 with offset greater than +42mm).

Thanks again; and here I was, originally concerned about clearance with the inside of the rim!

Thanks guys; that's pretty much what I really needed to know. I am pretty sure the brakes should fit the stock wheels, which have a hefty +45mm offset; in case they don't, I think a spacer would be the least costly solution, since I haven't been able to find good looking 18" wheels with a greater offset than +42mm.

I was aware of the concern over cracked rotors due to the crossdrilling, but I figure that with the sheer number of available crossdrilled disc brakes and kits out there, it must take fairly aggressive driving, such as that in serious autocross or circuit competition, to run into problems, and that's far from the way I will be utilizing the car, but I do appreciate the concern.

Now if I did plan to go into mild competition, I'd probably do something more like a new Mazda MX-5--and in that case, I'd be doing slicks, a roll cage and GT rotors instead of the SRP.


Getting back to the clearance issue one last time; does anyone know of any 18" wheels with 5x100 lug pattern that comes in offset higher than +45mm? I haven't been able to find any, buy maybe I don't know the right place to look?

You're right, now I'm confused.


According to Lance, to get more room for my caliper, I'd have to get a higher positive number than my current wheels' +45mm offset, i.e. +48mm or +50mm.

According to Rick, a lower number offset is necessary to push the spokes and rim away from the calipers, i.e. lower than the stock +45mm, like say +42mm or +35mm.

Uuuuhh........

Alrighty, got my wheels (Privat Profil by Konig), tires (Avon Tech M550) and brakes put on (only the fronts so far); EDIT: *snip* click here for my review of these brakes.

Rick, what wheels are you guys using on your tC?

-Ed

EDIT: Forgot to mention the car sits on TRD sport springs, so these pics are after the minor drop.
