You should get her down to Bedford Autodrome this Monday. Cheap track day on GT circuit. Be rude not to

Thats all well and good but will he be able to get on track though or will he be black flagged before he makes the briefing (noise)

In my view there is a down side, and that is with the bigger ramp angles and beefed up plates the car will push more at the front end in tight corners this comes more apparent on wet tarmac.. in the dry there is enough play on the sway bar settings to stop this but on a wet track I haven't been able to dial this out yet.

Oversteer is the solution on tight wet corners

Joking apart, I have not driven the car on wet roads yet but the slippy and muddy roads of Wales posed no problem. Car felt less skittish on braking that before and you could really apply the power hard on the exit.

The advantage is you can just about dial in how you want the car to drive with a nice set of passives anyway.

Any disadvantage can be dialed out with a bit of rebound shock adjustment.

PASM shocks on Porsche GT cars was the worse thing Porsche have ever done imo.
ALso it's what made me love my Cayman R's, the setup makes the R which really is the shocks, over a normal Cayman S !

They have even had to dump them on the CS GT4 race cars for passive adjustable units.

997.1 GT3 with the 3 things changed could be the best modern fun car to own I guess.

You can easily dial this out with the brake peddle. The driver is the glue that holds this set up together but it's a combination that's probably one of the most rewarding on 4 wheels

Agree in the dry I don't have an issue as the trail brake makesit all work. In the wet I'm just not getting the balance right and ending up with push. Only done 1 wet TD with this diff still need to practice.

Or just buy a 996.2 GT3 which has passives and 60/60 ramps as standard?

Stay with it and it will come together. You probably need to be taking more speed off before you turn in. There will be more grip on initial braking than you might think. Try braking to threshold/abs in a straight line for a while to get a feel for how much grip you have then brake 5 m later and take a trail in. That will do it

They have a 60/40 I think. A cup diff pack is basically all you need with a 996 and maybe a play with the pre load

60/60???

I would love to buy a 996.2 GT3.........and a 996RS and a 2.8 RSR and a 911R......but I can't afford them all so i'll just have to make do with what I have

Are you still getting on with that GT4 of yours?

A classic case of under rotation. Simply and easily addressed.
I can just see Cunno's next post ....

Right Steve, I did what you said and it was all going famously until the brake 5 metres later bit ...


This was moments after the rear end got "squirrely"



And this was moments after the rear got away from me altogether :



Any tips (apart from find yourself a good panel beater)

[Steve Rance]

Too much brake at turn in. Sorry, tough way to learn that one.
