Back from Spa ...........

Still in one piece thankfully, unlike the poor buggers in the black GT3 that disappeared backwards into the barriers at 100mph at the top of Eau Rouge ! Ouch ........ I'll post some piccies when I'm on my machine at home this evening - it was a pretty spectacular wipeout. The car's a mess but thankfully both occupants got away with a few bruises - the airbags did their bit !

The Colway Traxtar tyres on my new BBS split-rims worked really well. They claim to be 'scrubbed' down to 4mm, however mine had at least twice that ! To start with the car was squirming noticeably under hard braking, but that improved as the tyres bedded in. Overall I was very impressed with the level of grip - it really did not want to let go and when it did it remained surprisingly progressive, also I could not lock the wheels under braking. Grip should improve further as I take more material off the tread blocks. I'm going to run them as road wheels for a few weeks to wear them down a bit. At £40 a corner these tyres a definitely worth a look if you've got a set of trackday wheels.

I had also fitted a strut brace before I went out, and that coupled with the sticky tyres meant that turn-in was absolutely fantastic - no sign of understeer whatsoever, really impressive. I let a friend with a 968 Clubsport have a few laps at the wheel and even he was impressed !

As ever the main limiting factor (for me anyway !) was the brakes. They held up pretty well, and at no point did the pedal go soft, but the 3.2 brakes simply don't have the brutal stopping power of most modern sports cars. Lack of driving skill is most definitely a significant factor here, but the brakes really don't inspire the confidence to brake really late, and coupled with the relative lack of horsepower and lardiness (no weight saving measures on my car !) meant that I was usually the one being overtaken rather than the one doing the overtaking ! It's a bit frustrating to keep having to slow and go off line to let quicker cars pass.

Overall, though, I was remarkably impressed with the way the car went round what is the most fantastic circuit - the TV cameras really don't do the place justice, those hills are steep ! I was able to drive the nuts off it for 150 miles round the track, fill it with petrol then drive 325 miles home in great comfort. There aren't many cars that will do that without complaint ! At least 50% of the cars there yesterday turned up on trailers. A little more grunt wouldn't go amiss - really noticeable on the hills, but with a good set up and maybe some more braking power (new calipers would help I'm sure) then my little 3.2 will make a great track car.

Jamie don't buy new calipers repair the ones you have if they are under performing. ATE fluid and stainless steel hoses will make a big improvement if you haven't already tried that route
 
Bones,
Thanks, I will probably just go for exchange / recon calipers. I also know of a set of nearly new ones that are about to become surplus to requirements.....
I've already got Porterfield pads, stainless hoses and Super Blue. Overheating is not the issue with my car, it will stop all day long without fade. The problem is the actual braking power. My car is no lightweight (all the toys inc aircon), but with the extra grip offered by the wider wheels and sticky tyres, it will cope with more braking power - as it stands I can barely lock up the wheels. Weight is the key really, but I'm not prepared to sacrifice my creature comforts to create a track beast (yet .....)
Richard B is doing an interesting brake experiment at the moment and depending how it works out I may go down a similar route.

Jamie
 
Great report Jamie. Those tyres sound like a pretty useful alternative and I think your description of the braking characteristics/weaknesses is perfect. Even with a perfectly functioning system this sounds familiar. A more aggressive pad will give you a little more bite though. Glad to hear you survived - pity about the GT3. I really must make a trip to Spa...

Yep, I have fallen for big brakes and within the next couple of months will have 944 Turbo discs and 4 pot calipers on the front. Calipers are currently en route back from VCI following modification so it just remains to receive calipers and arrange install.

I will try std 3.2 rear calipers as they are only a little smaller than 964 C2 2 pot cailpers. The proportioning valve comes out and we can play with pads to adjust the bias. Keeping fingers and toes crossed this should be just about the right size brake set-up for a track day 3.2 - it is virtually identical to the 964 set-up but no ABS. It offers the same kind of stopping power as the Boxster caliper upgrades but has the benefit of increased thermal capacity from thicker and larger diameter discs. Also, its not as heavy as the 930 turbo brakes - which weigh a tonne - and can be done with the original master cylinder.

Will post all details when project is further advanced - and pictures.

Richard,
Looking forward to hearing how it works out. I'm amazed that no one in the UK seems to have gone down this route as it uses parts that are readilly available and not expensive (relatively). I wonder if a suitable engineer could be found to do the machining of the calipers / adapters over here ?

Jamie
 
Problem is, whoever goes first pays for all the trial and error - unless you can get a shop to foot the bill. I couldn't find one. I will get precise measurements of everything before its fitted to help whoever does it next though. With the current sterling/dollar rates, at least it is cheap right now to have the caliper mods done at VCI.

Here's what it looks like with the BBS on

That looks great - it looks meaner than with the Fuchs. I really like it - a lot.

I think your car demands a ducktail though and it could be a fraction lower, maybe just the front which is dead easy so you get the 1 degree nose down rake. If it was mine, I would also put Carrera stripes in silver or gold down the side - but I am a sucker that kind of retro stuff :ROFLMAO:

Cheers,
Richard
 
Hi Jamie

Glad you made it back in one piece.

I been thinking about removing my rear spoiler, but plan on keeping my front lip spoiler.
Did you notice any wayward handling with your current (spoilerless rear) set up on the track?

Cheers

Richard,
I agree, I think it looks really cool - proper 80's racer (minus wings though !) I intend to drop the ride height a bit, I'm just waiting to get the money together to get new sport Bilsteins, a full 4 wheel alignment and corner balance. It'll look even better with 245 rubber on the back and the 225 switched to the front. I've been toying with the idea of the Carrera stripes - I think it would look pretty cool in silver with the Fuchs and gold with the BBS. Where did you get yours from ? I can't seem to find them anywhere on the web. As for the ducktail I'm not terribly convinced - I'm not sure about mixing eras, it's a bit like putting Cup 1 wheels on a 3.2 - just doesn't look quite right (cue Richard's favourite picture of the mint green 3.2 with the ducktail and Carrera stripe !) Also not sure if I might have problems positioning the aircon condenser under a ducktail.

Anil,
I've not really had much of an issue with removing the whaletail, I think the scare stories are a bit overdone. The one area you do notice is in a strong crosswind at motorway speed, it does seem to get pushed around more than with the whaletail. That said I took it off pretty soon after buying the car and I never did a trackday with it on. I might try replacing it at some point for the sake of comparison.

Jamie
 
I got my stripes from (IIRC) Design 911 for some outrageous amount of money - like £110+. You can get them from Mike Zois off Pelican for about USD25 (again IIRC) plus postage from LA. Initially his design was not historically correct but I think it is pretty good now.

Mike goes by the user name of "mikez" and his email is 356@cox.net. I don't know if he has a webpage but a Pelican search will produce the goods and pictures of his be-striped SC Cabrio (with 3.6 and ducktail).

See here for tips on how to: http://forums.pelicanparts.com/showthread.php?s=&threadid=98717&highlight=carrera+decal. IMHO copious quantities of soapy water and a credit card get the job done (no filthy comments boys :p).

Jamie

Those wheels do look nice on it.

I agree with Richard re the rear wing - not so sure about the Carrera script though.

Nice car Jamie.
 
I know someone who is selling a 15" set of 3 part Ruf split rims for a narrow body Carrera.


They are very nice, but I just bought a set of Mille Miglia's.............. to go with the Fuchs!
