Track day 968 - Page 2 - Porsche General - PistonHeads UK

Do a quick search on this forum using the keywords '968 Clubsport'; they were discussed recently. Had things to watch out for - mainly belts, water pump and a couple of minor things. Pretty good car, cheap to run, good on track and don't go wrong that often.

The Clubsport had M030 (suspension and brake improvemets - bigtime) as an option You need this for a track car

Brake improvements? Sure about that? They were just the 944 Turbo 250 brakes, like any given 968, weren't they?

Thom, the front brakes with the M030 had cast holes and were enlarged to 304mm diameter

Thanks for the information

How come you see so many CSs with big red brakes then, Thom? Were they an option as well as the M030?

Dom, Big reds were not an option. Even with the M030 kit stopping 1400kg with 304mm discs overheats the system, so most fit 928GTS Big Reds with the 322 discs and enjoy all day track driving without the usual juddering experienced when the heat gets to the standard discs. The 968 & the CS all came with late 944S2 brakes which are marginal to say the least; only the M030 CS had 964RS rear discs fitted and 964RS size front calipers with 304 x 32mm discs (basically x drilled 928S4).

Not exactly; they came with 944 Turbo 250 brakes...or maybe you are talking about the very rare 944S2 limited edition called 'SE', aren't you? >> Edited by Thom on Friday 11th October 19:32

Well the brakes on my S2 seem fine to me - though it is slightly lighter than a 968.

Tron, I think if you look carefully you will find that the standard 968 and the basic 968CS have the same size pads on the front and rear with non drilled discs. I think it was only the 968CS M030 and the 951S (944 Turbo S) that had the larger 928S2 '86 Calipers, which are similar to the 928S4 calipers but have one pair of pistons that are slightly smaller. Of course I think that you could probably order a car with these parts fitted, but I do not know if this was in the option list. I know this is right because we did a customer's car that was featured in Porsche Post and 911PW, this had the small calipers and we fitted big reds on 993TT discs and had to make brackets to change the stub axle assembly from axial mountings to radial mountings. Right then everybody, your mission for the weekend is to crawl around car parks and look at 968 brakes...

At last somebody who tells the whole truth! (another precision: all the standard 944 Turbo MY89 to MY91 came with these brakes as well) No need to, you have summed it all up! >> Edited by Thom on Saturday 12th October 12:02

Thom, If you want to be picky, the 1988 Turbo S Silver Rose was the first 944 clone to carry the bigger brakes, then the 89 Turbo S, then was it not on all the 90-91 cars that had the 250bhp engine? Oh, sorry about the Tron, Thom.

As far as I know, there was no Turbo S in 1989. And you're right with the brakes: 944TurboS/944Turbo250(MY89-90-91)/968Lux/968CSNon-M030 share the same brakes. Please correct me if I haven't understood you correctly.

And you're right with the brakes: 944TurboS/944Turbo250(MY89-90-91)/968Lux/968CSNon-M030 share the same brakes. Please correct me if I haven't understood you correctly. Thom, To put the record straight definitively: 1988 944 Turbo Silver Rose, 1989 944 Turbo SE (250bhp), all subsequent 944 Turbo 250bhp models and 968 Clubsport M030 only share the big brakes. Late 944S2, 968, 968 Sport and 968CS (standard) all share the smaller brakes. Small brakes can be identified by the pad size being the same front and rear. If you don't agree, no problem, just get you knee pads out.

Colin, you seem to be wrong. "small" brakes: - 944S2 - 944 Turbo 220bhp "big" brakes: - 944 Turbo S - stock 944 Turbo 250bhp - stock 968 - non-M030 968 CS "even bigger" brakes: - 968 CS M030 equipped I have had the opportunity to examine any of these cars REALLY close together. (I suggest you walk down to your local Porsche dealer, ask them kindly to have a look in their PET, and see for yourself) If I am wrong, then you Brits are very lucky to have your own market PS: sorry if I offended you in my previous post, I really didn't intend to. I know that my knowledge is tiny compared to yours, but I'm sure of the few things I know. Edited: what is the Turbo SE?? Here it is commonly known as the British version of the Turbo S... >> Edited by Thom on Saturday 12th October 17:37

Thom I can only talk Euro as that is all I know, but: 944S2 1991& 968 standard front pads are 951.351.939.08 944S2 1991 & 968 rear pads are also 951.351.939.08. Same pad front & rear, both cars, ok? The 944 Turbo 1991, 944S2 M030 & 968 M030 use 965.351.939.03 front pads and 965.352.939.04 rear pads. These are the 965 Turbo 3.3 pads as used on the 964RS, and although the rear pads are the same size as the standard car I asume that they are a different compound or something. And that's it, I think. MAybe the US cars are different after all, but I can't comment on that one.

Colin, You are right about the pads, but actually I was talking about the discs! Sorry for this confusion. Still, these guys in Zuffenhausen seem to be pretty good at driving us mad! edited: so what is the difference between a Turbo S and a Turbo SE? >> Edited by Thom on Sunday 13th October 17:39

Thom For the record: 944S2/968 discs 298mm x 28mm front, 299 x 24mm rear, not cross drilled 944S2 & 968 M030, 951 250bhp (SR/S/SE w.h.y.) 304mm x 32mm front 299mm x 24mm rear, both cross drilled. Answer to previous question, the E. Sorry, I think some called the original 250bhp Turbo the Sports Equipment, hence the E, although who really cares, either way it was the hot rod version with the Koni sports suspension, etc.?

>>944S2 & 968 M030, 951 250bhp (SR/S/SE w.h.y.) 304mm x 32mm front 299mm x 24mm rear, both cross drilled. << The only discs with cast holes (they were never drilled) were the 968 M030

So why did they change the reference? 944S2: 951.351.041.01/02 968: 951.352.041.02 944S2(M030) & 951(250bhp): 928.351.044/043.04, not cross-drilled (like Dmsims says) 968(M030): 951.352.041.91 >> Edited by Thom on Monday 14th October 21:24

Sorry guys, I give up, someone else sort it out, lifes just too short......

Colin, I was going to suggest that we all apply for group pyschotherapy, me first!

Yes, thats' getting us nowhere but close to " -ness"! Still, I thank you for your conributions

A www don't stop I was going to print all that riveting brake pad information out to read at night, as its a guanteed insomnia cure...........

968 Clubsport - is it as good as they say on a track? I have been thinking of getting one for predominantly trackdays, anything to watch out for?
