you miss out on what the car could be, it don't need after market parts, it's just cheaper than buying CUP rear toe links.
they give us a car with GT3 adjustable sus which YOU cannot adjust !!!

The GT4 toe control arm is the same length as the S but has different bushing. Toe is adjustable via the eccentric but you can't get as much rear camber as required for track use of the Cup tyres without a longer adjustable tca.

Oddly the rear top mount is offset to the inside (not central) which provides extra camber over a normal central mount point. It does seem an odd arrangement, presumably for some clearance issue which is not immediately obvious.

Apologies for being out of touch with the PH latest.....do you still have your gorgeous Yellow GT4?

Yep, and now got a few choice upgrades waiting to go on :-) and a few trips planned.

Nice to hear you still have it - perfect spec...

How many miles have you covered now? Do you use it as a daily or just a track/weekend toy?

Interested to hear about the choice upgrades?

8mm front shims for LCA, Solid monoball adjustable rear toe links from Tarett and toe link locking bolts.
then in for a proper geo for a better fast road / track set up ;-)

Might get some Endless ME20 pads all round also, but at £800 that stings a little so will do a track day 1st to see what the oem pads are like.

Won't you need front toe links as well? Reading between the lines the US guys seem to be having to fit both front and rear toe links to get the camber they want to run. Adding the front 8mm shims is going to be in danger of giving you toe issues, is it not?

I was under the impression that Pagid RS29 was a track option on PCCBs

nope, good luck with that.

Ok so how does that relate to this statement then?

said:

However, as the frictional and thermal properties of iron and ceramic discs are significantly different it is important to use a brake pad compound that has been specifically developed for ceramic brake discs such as the Pagid RSC1. Some high performance brake pads, designed for extreme track use, such as the Pagid RS29 can be used with both iron and ceramic discs.

Good article in EVO this month. Track car of year. GT4 did a 1.03.8 around Blyton Park. Caterham 420R was 1.05.7. Radical RXC Spyder was their choice 56.15 History shows 997 GT3 at 1.05.2.

Doesn't seem to be available in the app yet. Good time, should be an interesting read.

They say the most talked about track biased Porsche in recent memory.

I don't think it will need front's, not going for anything crazy about -2.3 up front, people have got more than that with stock parts and 10mm shims..

It seems to be related to the number of threads shown per page. There are seems to always be one missing between the first and 2nd page.

Looks like there are 18 threads on page1 and page2 starts at thread 20 so whatever thread falls 19th (by date of last post) temporarily vanishes. Ive not worked out if its all page changes or just page1/page2

Good time to start a new volume.
