Auto-X upgrades S2

[Outlaw]

OK, Here's the deal. I've had this 89 944 S2 for one season and moving into the next. Through out the duration of this last season I switched to EBC green stuff pads, M030 swaybars and running new hoosiers, the auto-x compound(forgot the name, s04 maybe). I love the car but have somethings to address.
I must get a LSD! I have that covered, so no need to adress it. I also need more tire on the ground and I Just purchased some 17" cup wheels used on ebay for a good deal. I drove on them today and felt like they were causing brake fade, I guess from thier bigger size and weight . So now I will have to be looking into a brake upgrade. Is there a inexpensive way to do this? Are there some factory options available in like or other Porsche cars that will be sufficiant? inexpensive is preferred.
I'm also open for suggestions on how to pick spring rates for the front and maybe torsion bars on the rear. Oh yeah, I also installed KONI yellows this last year too.
I'm open to suggestions but please dont reply unless you really have good information.

A 944S2 shouldn't have brake fade at an autocross, 17" wheels or not, except under extenuating circumstances (extremely fast and/or long course, very aggressive left foot braker) or if something's wrong with the brakes. Have you replaced your brake fluid recently?

You might want to elaborate on your class rules and whether you want your car to be streetable before soliciting suggestions.

OK thanks for the input. I have not auto-xed it since the 17s were put on but I did drive it around on the street. It seemed like it was an over worked rotor and pad situation, Serious smell. I will look into the brake fluid too.
As far as mods to class or street application, I will be movong out of BS and into ASP. I know that there is little chance to compete with an altered Z06 but I must do something with the front springs. As soon as the front springs are changed, I 'm out of BS. So, the suspension is open for suggestions. In fact, I would rather build this car for a fun car and fit into the class afterwords. To be real honest, the car in stock for is not up to the S2000 challenge. There is more car there then the S2. Don't get me wrong, love the S2 but ready to make it perform better.
Thanks

I don't really have much more to say, but here are three related threads I bookmarked when I had a 951:

http://www.924.org/techsection/SuspensionPreparation.htm

My 951 had Koni Sports on all four corners, 968 M030 sway bars, and 250 lb. springs in front (I forget the torsion bar size, but it was proportional to the front springs). The car was still way too soft even compared to my Stock (Stock class, not stock) S2000, let alone an ASP car, so I'd go way stiffer than what I did.

Incidentally, the "S2000 Challenge" is no more -- the S2000 has been moved to A Stock. Some people think the 944S2 is one of the best cars in the new B Stock.

Sweet, thanks for the links. The only problem with staying in b-stock is not being able to change the spring rate. So, how can an S2 be that competetive? The front of my car will litterally touch the ground.

rumor has it (but I'd look into it more) is that is you keep the stock ride height, you can increase the spring rate as much as you want. I have heard this from several people but never looked into it.

I'm not sure what you mean by "touching the ground", but as for why it's competitive: lots of camber, wide wheels, and reasonable weight are a good start. A Stock (now B Stock) at Nationals was won in a 944 in 1997, and in 968s in '98 and '99; a lot of people who should know say the 944S2 is the 968's equal in autocross, trading off a bit less power for a bit less weight. The Boxster and S2000 showed up in 2000 to end the fun, but they've both been moved to AS for '05.

No, spring changes are expressly forbidden in Stock. The Solo rules are now available online for checking stuff like this.

WoW, I feel so clueless, I thought that the change of the front spring rate is not allowed in stock. This will help tremendoulsy. In the earlier post I mentioned that the front of the car touched the ground. That's exactly what was going on. Check out these pictures, they will tell all. http://racerpix.com/ go to 2004 season, b-stock , then Russ Coleman

[PedalFaster]

No, no, spring rate changes are not allowed in Stock.

And yeah, your car has a lot of body roll; my 968 has the same problem. I'm going to be cranking up the sway bar stiffness to compensate; my car has the M030 package, so I can stiffen both ends of the car since I have a Stock-legal adjustable front bar as well as the factory adjustable rear bar. People have won in the cars despite the body roll, though.

Steve

[Outlaw]

Ohhh, oops I got a little excited about the spring rate possibility. I think that the M030 option front coil over set up is better then mine. Isn't the ride height adjustable? I still think that it would be more fun to set the car up to be more fun to drive rather then trying to stay in the stock class. Sure, I know, some newer Z06 or 996 is gonna come alone and rip me a new one. With a stiffer front end and torsion bars, I think that it would make for a more fun car to drive.

[PedalFaster]

Yeah, the spring perches on the 968 M030 front shocks are height-adjustable. You unfortunately can't use the height adjustment feature on a non-M030 car in SCCA Stock unless you do the full M030 package conversion.

I totally understand your desire to make your car fun, even if that takes you out of Stock. Isn't fun why we all do this?

I do it for the parking lot suntan!

What is left of the M030 option? I have the swaybars and limited slip?

[PedalFaster]

I don't know. I have a 968, and I know that besides the normal suspension culprits, the knuckles, front hubs, and front brakes are all different on the M030 cars.
