I'm sure -3 at the front is fine, however my point was as you're, by your own admission quite new to trackdays I'd go slightly less aggressive until you understand the car under you then make your choice. Geometry isn't going to find you seconds of pace, it's there to give you a car your comfortable driving hard at the limit and a balance that suits your style. For instance my setup works for me, but everyone that drives my car is scared by the rear end being so loose. Now that is a result! yes! had to pay up for em a bit, but i thot best to buy them while they were there. they seem rarer than rocking horse sh*t! tho they do come with mich pilot sports , so can use them for an airfiled tuiition day, as a set i can destroy! (unless they're in good nick, which i doubt). spoke to donnington, they souhld be posting their calendar for march soon, so will mail u if there's a date that loks suitable. am going down to see amate of mine who used to rally (international), and we'll go for blast round castle comb which is near him (i "think" i trust him with my car). ...anyway, he sent me this clip of CC from utube, to make me at ease.... oh, and i ordered those books form amazon u suggested, thx for that. cheers Nick

fwiw, found a solution to one of my problems... found a breakers breaking a 968 and the original wheels are intact (most of the car's intact for that matter!) So i'm going for those. cheers nb

yes, and to be entireyl frank, it saves me takign a day off work (which is going bananas), as they are in kings langely and i can drop off in mrng and get train to Ldn form there. i spoke with Calum who thot 3 was fine for front. and many of the 968 chapsrun 3 at front. everyone i spoken to say jzm know what they're doing with gt3's and 968's etc, and are v good. So for now i'll use them for initisl set-up, run it thru the summer and take to your man at hemel in the autumn for reviewing.

ok... according to these guys http://www.dymag.com the ratio is something like 6:1 (tho of course they're trying to flog wheels to you), but is similar to JZM figure. I suggested a progression in terms of tightenting up the handling. JZM think they know best . Have even been tod by someone that after setting up the car for him, they refused to tell him excavlty what settings they used, because it was their "intellectual property". yeah... When Calum Lockie drove my car, he said it could do with 2 to 2.5 deg of camber. So i'm going to tell JZM to add a deg and take it to two. Steel top mounts not a bad idea, so i go along with that. net net, i agree, i want to keep the car relatively tame. So will get jzm to set-up, run it this year, then when i have a better sense of what i need//want, i'll take it elsewhere. i think he has a point about the wheels, and i'll just run the 888's on road, and see how it goes. and be patient to find an orignal set. and one of the above coments aobut the o/set changing the handling is what Don Palmer told me. I had a day with him last week. I'm technically challenged but i thought he said that the pivot point of the wheel is fixed, so a different o/set means you get a different contact patch on the road. his adivce was stick to originals. all your advice and help is very very appreciated. Nick

ok.. been speaking with JZM. THey'll do the track set up, apparently need unibore top mounts in order to get 3 camber. also they say replicas weigh about 2-4kg more, which (and i',m a bit thick when i come to physics..) he says means equivalent 100kg on the body.

hi Jon, thx for that. i always want to use it on the road, but i dont have to, so I'd like to do about 3-5k miles pa on the raod (if i ever get the time!). Oddly, the only aestetic point about the car i think could be better is the front wheels, which altho they sit close to the top of the arch (and next geo i will probably lower the car again), they do sit some way inside. In other words, if i just wanted it to look better, i'd consider spacers on the front wheels. I've also been told by the guy that did the geo for me recently, that if the tyre does threaten the arch, then he can "bend the arch back" with a tool, which involves no pain (supposedly....), ie u keep the panel on and gently bend it, was my u/standing.

hi Tony, the tyres are 225/45/17 front and 255/40/17 rear. i've spoken to a couple of people who do geo set-up, and they thought it would be "ok". But i want to be as sure as i can. however, my basic plan is to use the original wheels (with toyo 888's) for track, and have the car set-up accordingly (and it wont be an agressive set-up by a long way). Then use the replicas for road. Thus, as long as the set-up wasnt affected too much, i'm thinking i could live with a sub-optimum set-up for road use, provided it was only by a small margin. if that makes sense.. !

hi to all, am new here and wondering if anyone can help. I have porsche 968 club sport. I'd like a 2nd set of wheels (17") , so i can have a set for track tyres and one for road tyres. Getting hold of another set of originals is proving tricky (esp as the fronts are 7.5" which i believe were unique to the 968). So ive found an outfit called PWS who seem decent. They sell a new set of replica wheels, for a reasonable price, but the off-sets are different: front 7.5" original ET 65, replica ET 52 rear 9" original ET 55, rep ET 47 So what i need to know is to what extent the wider off-set will affect the geometry/set-up, because i want to be able to swap the sets of wheels, w/out havng to chg the geo (every time!) or affecting the cars handling in a material way. any suggestions wold be much appreciated thanks Nick
