Who's using what ? Quantum two price or other brands? What do you like/don't like about them. The quantum's seem to be the easiest to install.

DOUG @ ECS

I would only use the ECS spindle ducts on my personal car, although I might be biased.

I installed the Quantum last weekend, not so bad install and was pleased with with the quality of the parts.

A cutting bit in a Dremel to enlarge the duct hole in the wheel well and grinder with a thin cutting wheel to cut off the wheel sensor bracket are needed. The one tool I did not have was a Torex T55 bit to remove two screws from the hub.

The kit mentioned above looks similar if you cut the bottom third of the duct mounting bracket off so you don't have to remove the lower hub mounting bolt/hub. The Quantum also has an aluminum ring installed on the plastic duct that provides a more stiff diameter for clamping the duct than just the plastic.

Next track event is Sunday with fresh rotors.

I made my own last year because I could not get a response from anyone at the time.

I used a Quantom kit. I think its working great!
I had to cut bigger holes for the duct, like mentioned above (did a crrrappy job...) as well as cut some hose so it didn't rub the wheel.

If you are referring to a C5, C6, or C7, Corvette they do not have spindles. They use knuckles and bearing-hub assemblies.

Quantum is my choice for a brake cooling duct system.

I only used one duct piece (cut in half using one half on each side) of the two duct hoses supplied and it looked tight lock to lock of the steering.

I used the quantum spindle ducts with the Fog light kit and they worked great!

I'm running DRM molded ducts from the OE ducting into Quantum spindle ducts. Clean install, seems to clear 285 18" unless I'm at full lock.

Hat_Trick_Hokie

This is exactly what I'm waiting to install on mine. Does anyone run DRM ducts with 315's on a square 18" C5Z wheel setup with success?

JDIllon

This setup works great!! And is about $50.00 in parts. There are several of us that have installed this setup here Fl. the intakes are located in a high pressure point.

If you decide to go with this setup? I have done several, call me if I can be of help. JD

I used 315 Hoosier A6's all around on c5z wheels with the DRM ducts at my last event last year at NJMP with no issues.

Quantum Ducts. Work great !

I just put the quantum ducts on my C6 GS, I run 18x11 up front with 295s and it rubs a bit at full lock.

I did appreciate that it includes heat shields for both the dust boots that usually melt (tie rod and ball joint).



I also zip-tied the hose to the control arm to get a little more clearance, but in all honesty I don't think I bought myself more than 1/2".

What hose are you using? The one I have is too rigid and I did have one side come off at close to full lock.

But the duct extensions did wonders at the track. My oil got to 288F and I was running the car hard, two people on board, on XP10 and XP8 pads, ATE DOT4 fluid, and the brakes never had any fade. Pedal feel was affected a little at the end of my fourth session, but that was due to fluid getting contaminated/boiling over. Time for SRF!

I have DRM ducts with LG aluminum brake vents. They require separation of knuckle and bearing assembly, but all you need is to remove the ball joint nut (and lift the assembly off the bj, don't try to pry anything off) and remove three T55 bolts. Not as scary of a job as some on here paint it to be. And it lets you remove the wheel sensor bracket in its entirety, without having to cut it out.

OP: Get a kit, any kit, and you won't be dissapointed. Having confidence in performance of your brakes will do wonders to your times. It did for me.

LG ducts hear.. love them work perfectly run 315/675R18 Pirelli's no issues.

Ended up talking to Doug from ECS and i got a set of their aluminum ducts coming next week!

ScaryFast

Link to Quantum part? I did some searches but didn't turn anything up other than a couple of ATV and motorcycle places.

Nevermind...apparently they are now called Lambert Automotive.

ImHuntingWabbits

That hose came with my Quantum kit, looks like it can be purchased separately:

I have the LG Spindle ducts mated to a Doug Rippie brake duct kit.
