Curious if anyone has any recent feedback on the Giro Disk rotors on the street? My brakes are pretty solid as is, but with more power I want to start addressing suspension and brakes.

90% of my drive time is on the street, sometimes quite aggressively. The other 10% is on the track. For now mostly straight line 1/2 mile, but I want to get me feet wet on a road course (but I'll start that endeavor in my E46 M3)

I want to see if the Giro Disk upgrade is worth it for me or should I just get some nice pads, SS lines, and good fluid

 

For the street, stock brakes are more than enough. I've run and sold countless sets of Giros over the years. They are a good product and will save you about 20lbs of unsprung mass for 4 discs over OEM. I have a some extra new in box sets that I'm not using if you need some at a decent saving. Giros work well at the track. With good pads and fluid like Endless RF650, you'll have a great set up. Good cooling is probably the most important aspect of a good brake system. Get some good ducts, 996Cup ducts are the largest and most effective. You can see those below along with the upper 997GT3 air guides. Don't forget ducts for the rear especially if you run with PSM at the track. Don't waste your money on steel lines even though everyone wants to sell them to you. Biggest scam out there but there is a good profit margin in them. Look at what Cup cars run, same stuff that's on our cars. Contrary to what people think, stock lines are not rubber but rather composite mesh encased with rubber. The stock lines are good. For all out track duty, I highly recommend British steel AP racing rotors. I run their 380s and it's top notch stuff used widely in IMSA, NASCAR, etc. They are fully floating both axially and radially (Giros only float axially). AP is pricey, but the best...

I would use Giros for your setup..

Strange as checked with AP racing and they say there is no AP product for 996tt... Went with 350/350 Giros for next year till will upgrade the calipers and move to 380/350

 

There is a 996/997TT application. I can get the AP racing stuff through my US distributor. I don't think you can get it in Europe however.. I run the AP 380/350 GT3 stuff but can get it in TT offset also. Same with 350/350. The AP stuff lasts quite a bit longer than Giro under hard track use. For the street it doesn't matter. Both are overkill

 

hey john...is 6x4 overkill for the street? and is the 6 pot front most use just a 96gt3 brembo? thx

 

With proper cooling the stock 4/4 brakes are more than enough for anything you can throw at them on the street. The piston area is the same as on the 6/4 350/350 set up as the 6TT 4/4 calipers. The yellow 350 6 pots are 6GT2/3 calipers, the red version is a 997TT caliper. The GT version uses zircon piston puck heat insulators while the TT pistons are just steel. The yellow 380 997GT3 380 calipers that I run are physically slightly larger while using 20% less pistons area than the 996 cousins.. The 997 rear calipers are larger and have 50% more piston are than the 996 versions.

 

thx.. without going again into what type of "streets" i find myself on, i'm just trying to figure out whether or not the 6x4 combo would better suit what i do..and i bet it would, but stopping has never been an issue. but its too late as i have new painted stockers headed my way soon enough and should've considered that sooner. probably why i wasn't able to give those spare parts you had/have much more than a cursory thought as i'd already partially paid for the stockers to be redone! thx for the reply/info.
