I think the max negative camber is -1 plus a tidge at the front and -2.5 at the rear. I also am running MPSS tyres but have PCCB brakes. The only complaints I get are from passengers who think we may not be able to stop .. and the singing from the tyres .. Would I go for PCCB's on a GT4 with GT3 steels ??? All I know is that the standard CR brakes are not quite up to the job .. for me.
Cayman GT4: Where are we up to now?

330 stock plus your 30bhp from upgrades , it's not all about bhp though, as I stated the mid range torque on my Spyder feels loads more. Cost for a nice manafold is £2.5k and £700 for a map.ORIGINAL: spyderwhite360 bhp from a spyder/r has got to be the way if the gt4 is to expensive or not all that! What would the cost be to get 360 hp and I thought a remap plus manifold/exhaust upgrade would only get an extra 25-30 bhp?ORIGINAL: MrDemonI run RS29 in my R and -1.2 camber with pilot SS tyres, it is about perfect. the extra power would come from changing the manifold to convert 4x 400 cell cats to 2x 200 cell cats add that with a remap for about 360bhp. The shove in the midrange is a lot more drivable. if you went my Spyder route on the R , then wow .ORIGINAL: CLIFFWILKINS Cheers Jeff. Looks to me Pads are the only the worth while upgrade then . Pagid yellows? or something? Expensive for 13 bhp No issue with The Rs driveabilties. Might not notice 13bhp [] Obviously pretty much perfect the Cayman R then.[
Remember I run a far better pad to your EBC padsORIGINAL: Andy FaganHmm, I've done it umpteen times from far more than 120MPH and I find it is perfect. Too much travel on old MC you'd need to be a contortionist [ORIGINAL: MrDemonSitting in it and then stopping it from 120 mph for a perfect heal and toe from 3rd to 2nd is a whole new story. I have driven another R with giro disks and the GT3 MC and it was the same as my PCCB set up, the brake pedal travel is too little so come heal and toe time the accerater for me was too far way from the brake once the brake pedal does not move that much , which is all the GT3 MC does. I can do it in my SPyder which has the 6 pots and bigger MC but it's far easier to do in the R when the pedals are level esp with size 7.5 feetORIGINAL: Andy FaganCompletely disagree with that. You sat in mine!! the pedals are perfect (For me anyway) [ORIGINAL: MrDemonI would not run the GT3 master, as it moves the pedals out of sync for heal and toe, RS 29 pads gives you the bite and feel you need, had no issues at all with RS29's with standard MC.ORIGINAL: CLIFFWILKINS Cheers Jeff. Looks to me Pads are the only the worth while upgrade then . Pagid yellows? or something? Expensive for 13 bhp No issue with The Rs driveabilties. Might not notice 13bhp [
so never had an issue with my pedal going to the floor with rs29 pads and motul 660. I was going to fit the MC but after fitting the rs29 there was just no need.
There are a number of tuning posts on Planet9 including this claiming 370hp http://www.planet-9.com/987-cayman-boxster-modifications/87393-987-2-tuning-dyno-results.html My 981 has been on Regal's dyno and they are professional bunch so I would believe numbers from their dyno
A 6pot with 350mm disks and rs29 pads should match our PCCB set up. I will go PCCB if the cars got 4 pots, but if it has the 6 pot and 350mm disks, I'll save some money and just fit rs 29pads. Porsche do state for a track car steels are better after all unless you have deep pockets to replace ceramic disks. Depends if people are going to run this as a road car with a couple of track days a year, or make it a track whore.
Regals over reads.
so interesting to see what you got for your 981 over Porsche claim. Surry rr on the same car got 350bhp, (20bhp less) then BOb had a true custom map from a expert for his car and got a real 365bhp at Surrey RR, I have driven his car Surry RR can always take a smile off people's faces lol. But 365bhp at Surrey RR for a R is a great figure.

] [] [] Haven't been running EBC for a year now. I use Mintex M1166 and they're fantastic [8D] and Castrol SRF I've done a lot of research and development on the brakes and have got them to the point I'm happy with now. GT2 ducts, SRF, Mintex M1166, Titanium heat shields and GT3 MC. PS: Have you booked on the RS day at Oulton for 2015?
Yes but they don't do Porsche RS days at Donny and Cadwell. You should book at Oulton March 2015 it would be a good yardstick for all your mods!ORIGINAL: MrDemon I tend to do Cadwell, Donny and saving a few pennies for a few euro trips in 2015, Hoping my GT4 will be here May ish. Oulton is 4 hour round trip, I did try and get to the PCGB track day but 4 hours is too much time out. Good to see you ditched the ebc
Very interesting stuff. At a glance, there is not an awful lot of difference between the spec's of the old R and the new GTS. Has anyone owned both - how do they compare? It's very tempting to assume that the GT4 is going to be significantly ahead of the already excellent GTS and R as far as a hard-core track/fast road cars go. Should be really special indeed.
Many of us R drivers have driven the GTS and come away keeping our R's. to spec a GTS even like the R you have to spec X73, buckets etc and you are still left with electric steering and over servoed brakes. Get back in the R and the car just feels more alive and direct with more feel and better steering by miles. Depends what people want from a car there is a reason a group of people buy the 996 GT3 for the feel etc even though today it's a slower car. and a reason 997.2 GT3 RS have gone up 70k in 6 months due to the 991 GT3 being just another super car. for a fact the GT4 cannot and will not match the steering, and that's 80% of the joy. yes the GT4 is going to lap faster, but lap times are not what driver fun is about. It's going to be tough choices to sell an R to buy anything new Porsche make atm
There seem to be lots of views about different dynos and owners' motivations so this story is an interesting one. Reading the full thread and the subsequent PH one, it seems TheBob is well balanced with his comments re different dynos, including that the Surrey Rolling Road is conservative. Also the PDK cars were slightly down, and OldBob has some further comments at #4 thru #8. The thread link is http://www.planet-9.com/987-cayman-boxster-modifications/88029-surrey-rolling-road-results.html#post778518ORIGINAL: MrDemon Regals over reads.
I'll see, my mods are just a personal choice to make the car feel better for me and the style of driving I like. Not really a fan of the RS day, it's very clicky and it's always shit weather. I like the 964 Porsche run day at Donny, but it looks like that might not happen in 2015 !! less bragging rights and lap times more fun and nicer weather. to many trailered race prepped cars on the RS day many with slicks shod cars , not really my thing.ORIGINAL: Andy FaganYes but they don't do Porsche RS days at Donny and Cadwell.

Good reply, David. Thanks
I go on track days with the club and others such as Goldtrack and Circuit Days. There are generally a large proportion of track oriented cars, some of which are running on slicks (particularly at Spa) but I agree with Andy on having fewer slower cars does help. I find it really interesting between runs to chat to all the other participants about cars, maintenance, modifications and whatever. I have never found events to be cliquey to the exclusion to chatting to other enthusiasts and get to sit in everything from Radicals, McLarens, Cup cars etc. I generally book well ahead (being retired) and the weather is of course a complete lottery but that just adds to the varied driving experiences. I completely agree with the points about mods being a personal choice, and it not being all about times, for me it is about being able to improve skills particularly in reading the track. Improving this skill is particularly useful on new tracks which for me this year were Thruxton, Snetterton, Rockingham and Brands. Luckily my 'wet' days this year have been only at Silverstone; Goodwood in the wet with its lack of run off can be rather intimidating. Anyway somewhat off topic so I better stop.
when you say "having fewer slower cars does help" on that event you are the slower car lol But it's mainly the March booking which puts me off it, I have never known it to be nice weather for the RS day. And at £600/700 a pop all in tracks days are expensive places to be.
As you say, it is not all about the time - or ego. I help faster cars get past, it's the Monaros and AMG saloons that are slower overall but heavy footed on the straights that are frustrating for all.
