Question from a Numpty new GT4 owner

[Scooty100]

Cars great, 1500 miles under my belt now with the only niggle being a hint of understeer .
Now I appreciate the cars are set up like this out the box but now my cars close to run in and the tyres are scrubbed up I want a little more turn in.
The mileage has been mostly done on wet roads so maybe I'm being a little critical ?
Anyhow prior to its 1st track day next month I'm thinking of taking to my opc and asking them to make an adjustment to one of the ARB's . Question is what exactly should I be asking them to adjust Based on my requirements ?

Tks in advance and once again I'm a Numpty !

That depends on when and why you are experiencing the understeer and you level of experience or ability. Whatever the answers to those questions do not take your car to an OPC for a set up solution. It is not a skill set that they are trained in and the result will not be satisfactory. Take your car to a decent Porsche specialist tuner and ask them to do it and if they don't ask you essentially exactly the same questions mentioned in line 1 of this reply, take your car to another specialist that does.

Tks Steve. The understeer I feel more at speed where the steering feels very light . I'm a fairly keen track day goer, average ability not very mechanically minded.,
Have always had my GT3's setup by recognised Indis but I thought the beauty of the GT4 was simple adjustments of the ARBs. Again I'm not mechanically minded so forgive me if I'm totally incorrect but In the Harris video they adjust the ARB settings to suit his driving style . Didn't seem that technical

It's exactly the same process as your GT3's. You can ham fist something with a bar change but to do a set up properly you I'd get you base geo done first and then trim the balance on the bars.
