A few of us worked on our cars pretty much all weekend...
A few of us put on StopTech rotors and steel brake lines... One of the guys received two right rear rotors from StopTech [img]/images/graemlins/freak3.gif[/img]
It wasn't too bad - but the heat index up here was about 105...
Put the shifter and a few other of the poser mods on - and also dropped the seat two inches... All that is left now is the VEC1 tomorrow night - and the exhaust hopefully Thursday - and then heading to ViperDays Thursday night...
Went through the break-in procedures last night with the StopTechs...(60mph to 10mph hard - repeat about 20 times until smoke and smell...) Good god - it is absolutely insane how big a difference those are from stock... Dam near need the 5-point on to stay in the seat...
So anyways, after a pretty intense weekend of working on the cars, I think it is about ready for the track...
The steel brake lines are pretty easy to do too - a little hard to get wrenches on some of the bolts - but no biggie...
I also greased the car up - you all need to serious do this... I was amazed at how little grease those bushings had - and it just came fromt he factory! Anyways, there are three fittings per wheel - get them all - two on top - one on the bottom...
We also took the shims out of the front to get that extra 1 degree for faster cornering... All in all - a hot long weekend and the ACR is off the stands... Wait until the other guys get the invoice I send them for using my garage [img]/images/graemlins/supergrin.gif[/img]
The StopTechs don't really do much in the way of shorter stopping distances. Basically, all that work is tire limited. The StopTechs, however, do a wonderful job of giving you consistent and repeatable fade-free stops lap after lap.

There are hundreds of Stop-tech owners who would vehemently disagree with you on that one.

I understand that about the whole brake package, it's just that they were talking about having installed only the rotors. Hard to see how that makes any difference.

I wouldn't though.
They're placebo warriors. Stoptech was one of our major sponsors and I think they are a great company with great service. But brakes are basically brakes and the car only stops as fast as the tire. The biggest benefit of big brake kits is that they don't fade.
Eric, I misread the original post and was under the impression that the 4-wheel kit was installed. Rotor swaps resulting in shorter braking distances is just absurd. Modern day pads don't outgas enough for them to be an issue.
I have the Stoptech 4 wheel big brake kit and it sure as shit does reduce the stopping distance dramatically. Ive had rotor swaps in the past and noticed no difference with just changing pads/rotors.

additional thoughts...
some replacement rotors are built differently... different masses, fin design, weight etc. Things that do make a difference that will increase overall braking performance over multiple braking sessions.
Another thought...If a person puts on a new set of tires and lighter wheels..the stock system will perform better than putting a set of "aftermarket" rotors on with the heavier wheels and older tires.
Smackie has good points...it's the whole set up that makes the difference not just some "poser" rotors.

Ya know, the same thing happened to one of the guys up here. StopTech's QC must be going right out the window too because when he called to ask them about it one of their reps assured him they sent him the right parts. Psssha, whatever. Oh well, pimp factor is up a couple notches and unsprung wirght is down a little.

I agree totally - there is a mechanical limit and if you can lock the tires with stockers (you can) then aftermarket don't help. It can help brake "feel" which may help ability to extract the best performance, but I don't think any Stop-Tech equipped GTS's are going to be stopping like SRT's, tire for tire that is (no slick'ed GTS's)
Well, I am here to tell you that those rotors and race pads made quite a difference when out hammering on it... It was quite dramatic to tell you the truth... I could stand on those brakes going 100 and the stopping distance was far shorter than stock - VERY different than what I had done with that car stock - and the RT for that matter... As a matter of fact - I did it about 20 times during the break in...
They are slotted - which also helps dissipate the heat compared to stock. That combined with the steel lines hopefully decreases the odds of slamming into a wall with no brakes... They weren't purchased for poser mods - I doubt anyone would even notice the difference for a visual aspect...
As far as slotted and going through brake pads - well, when the race pads aren't in - I doubt going through a pair or two of brake pads a year is going to cause sleepless nights...
Well see, I head out Thursday night for ViperDays... I will make sure and pass some of the comments along to the techs and see if they have any input...
Just a related thought on brakes. Does it seem stupid to anyone else here that only about the last 6" of fluid in the line and caliper take all the thermal abuse while the rest of it back up to the master cylinder just slacks along for the ride? Don't tell me there's convective circulation in that small of a line ... no bloody way.
Why doesn't someone (race application only) make a recirculative system with a cooler in-line. Sure it'd be a little complicated, but it's not rocket science. When you're on the brakes the recirculation mechanism closes a valve to allow pressure to actuate the calipers. When off the brakes the system opens and recircs. I can even imagine a way to do this convectively so as not to need pumps. As important as keeping brakes (calipers) cool is in racing, I'm surprised somebody hasn't done this.
Agree - there should be two lines keeping the flow going through the brake area...
You should have smelt those rotors last night - following the break in procesdures - they turn blue from being so hot - and smoke... Seriously, even SB was giggly after seeing what those StopTechs were able to produce...
I do realize that you can only stop as fast as your rubber - but these are a different beast compared to stocks... Maybe the stocks just never came that close to utilizing as much stopping power...
I'll take Par out next week when he is back here - and then he can be the forth person to realize a serious difference in stopping that beast...
StopTech - about $1,300 for rotors, steel lines, and racing pads... Pads take about 15 minutes to do - so put the greens on afterwards...

Now I am not positive on this, as I got limited track time (but tons of drag strip time) in the GTS and none in the SRT (no roll bar). However, I distinctly remember that Woodhouse had added a recirculating brake system to some of their race Vipers, including Pemberton's. I don't believe it had a cooler in it per se, but I do know that it was designed to make ALL of the brake fluid "share the heat". I would be happy to get further details if anyone is interested. I would also guess that Smackie knows more about this system as well. Of course, I could be totally mistaken (not the first time) and this could have been something different than what you are talking about.
In the meantime, I will have to relegate my Stratomaro2000 to the drag strip only. Can't quite afford the roll bar at this point for track time, even though I suspect it would be a blast. [img]/images/graemlins/gr_driving3.gif[/img]
