has or is anyone road racing with 1LE brake calipers?

i will soon be road racing and i have 1LE's up front and LS1's in the rear... i wanted to know a good brake pad and what brand fluid you are using if so..

 

Dave, Are you going to be running on racing tires or street tires? - it makes a world of difference what pads to run.

The added traction of racing tires will produce much more heat into you brakes and racing coumpound pads like a Hawks "black" (M) compound and airducts are always an added plus not only for rotor temps but for cooling the wheel bearings.

If you are running street tires and just having fun there is no way you are going to maintain decent grip and a Stillen Metal Matrix pad will be perfect- ducts should sstill be added though. Just get some Dryer (as in Washer and Dryer) Duct hose for Home Depot and try and mouint it under there to route some air onto the center of the hubs. Zip tie them to the spindles even- be creative.

 

hey Dean..

well i think im going to use Kumho ECSTA V710 since my friend at dicount tire can get them for 40$ under tirerack prices.. (about 160$ a tire)

so those, some blue DOT 4 fluid my friend gave me that he uses in his road racing STi,.. home made brake ducting.. and im still not quite sure on the pads... i was hoping it would be a decent caliper to use.

 

I have met many (more that 5) racers that wheel-to-wheel their cars on 1LE's. I have not asked what pads they're running...but 1LE's is all they can run in their class.

 

Calipers are not the main problem with heat, its the wheel bearings.

 

You can actually put down the rotors are first - they warp quite easily, but are relatively inexpensive. I actually think the PBR calipers (1LE/C4/C5) are some of the best 2 piston designs made by any car manufacturer, they do nicely in road race/autocross.

I'm sure the bearings take a nice beating also.

A good brake cooling system is necessary to keep the rotors cool and keep the fluid from boiling, other than that you really can't do that much besides go to better parts (6 piston Baers with Eradispeed rotors are top of the heap). Of course it depends on your race series - most are pretty specific about brake systems.

 

I don't think you'll like the V710's in a road race application. 710's heat up very fast and autocrossers and having to water them down between 60 second runs to keep them from over heating and getting greasy. There also very touchy about air pressure, 2-3 psi up or down on one end or the other can really through off the handling. I've autocrossed on 710s all year and love them, but I wouldn't use them on a road course.

If you want a R-compound take a look at the Kumho Victoracers, Nitto 555 RIIs or the Hoosier 05 Roadrace compounds.

 

thats some good info... i'll check those tires out ....

 

The Kumho VictorRacer is a great road racing tire and its DOT street legal (I know, I designed it), however, it comes with shollow groove depth. Its always best to go to these events with two sets of tires, one set has shallow groove depth for dry running, while the other set has full groove depth in case of rain.
For full groove depth the BFG KDW tire is awesome.

BTW: If you buy the VictorRacer, the size you want for your Camaro is the 265/45R16, this size is unique and was designed specifically for the Camaro. This tire won me an SCCA National Championship in 1995. Yep, that tire design is slightly over 10 years old. Hard to believe.

 

I beg to differ. I have them on my Camaro right now and they are a piece of crap. I am going to pull them off and give them to my Mother-in-law for her Toyota Avalon before next summer and I am going back to the Goodyear GS-D3's

 

looks like Dean is back...


what about Avon Tech R's? i was reading on tirerack that these are pretty damn good..

 

whatever happened to trying the toyo's?

 

I got to thinking striaght that it would just not be a safe option on the car considering its my wifes daily driver and I hardly drive it. If she were to hit a good wet patch of road she could be into trouble.

The Goodyears were a great tire and I realise just how much when I put the BFG's onto it. Plus the Goodyears look so much more aggressive and wider, they fell much more stable, and they are miraculous in a very heavy downpour without hydroplanning when everyone else on the freeway was in a scary instant i had last winter with the freak terrentual rains we had here in So Cal. I was moving faster than the other two cars coming up on them and yet I was able to steer around them when they both spun and one came into my lane on a 5 lane freeway- the water was streaming across the freeway like a river on the 57fwy north just past Imperial Hwy. The Goodyears are great wet and dry.

 

Can't say I've ever met a Goodyear tire that I've like. Course everyone has differnt ideas of what's good.

 

99% pf Goodyear tires are overpriced and Goodyear uses hard enough tread compounds so they last and you feel like you at least get your money's worth milage wise.

The F1 GS-D3's are a different breed- they finally nailed it with a "Good"year. Try it, you'll be pleasantly surprised just like I was, I too always hated all other Goodyears in the past like their OEM Vette tires on the C5's to their Eagle GT's to their radial passernger tires I still have on my El Camino that are hard and slippery, but last long.

I will give you the most trustworthy and factual reveiw on tire performance on these boards.

 

Have you compared them to a KD or just the KDW tire? I have the KDW now and was looking at KD, but they're so expensive.

 

KD "were" the top gun in dry traction tires, but have always been terrible in wet conditions, matter of fact they can be downright scary and unpredictable in rain.

The new top dog is the Yokohama Advan AD07 if you are going to 17" rims, Otherwise the Goodyears are still my pick for 16" rims.

here's some actual test times and measures on Advans vs. the G-force KD-

Those Yokohoma tires are $209 a piece....not an investment to be taken lightly.

 

V6#20....Dean right? Just updating my user ID book...

Ed

 

Yep, I think it was CChotrod again that clicked me off again. I just get that out of the blue ever once in a while now.

Look for

v6#21 and so on.....

I started with #20 because I figured it was about that many names by now. I have never had any problems ever on any other boards but this one.
