Collective Advice Required...

Recommended Posts


I have a 99 Carrera 4 Coupe fitted with the Sport Techno wheels and the Porsche fitment Pirelli tyres that come as standard (295 rears).

Since fitting them the car seems to ride quite high on its suspension, so I have made the decision to install a sport kit that will lower it as well.

I have been recommended the X74 kit from Gert, but just wanted to know if any of you have had good/bad experience with this kit or if you would recommend another kit because of clearance issues created by running larger wheels.

All advice greatly appreciated.

I don't think the X74 will fit a MY 99.  It is for the MY02 and newer.

That is correct. The newer cars have additional chassis supports welded in.

X74 is not approved or recommended by Porsche for any cars older than MY02.

Thanks for the wisdom guys, Gert emailed me yesterday and recommended the X74 kit and he was unaware of any issues with installing it.

Glad I checked here first before spending my cash.

What other options do I have instead of the X74?

The ROW M030 is suppose to lower a US car with the standard suspesion around 20 mm in front and 10 mm in the rear (seem to vary +/- from car to car though). However, considering you are in the UK and already have a suspension that is lower than the US suspension, I doubt you you will get the 30 mm lower all around. Other alternatives that would work would be the various coilover suspensions with adjustable right heights or a "lowering" spring combo with your shocks (not recommended) or springs and shocks that are matched.

hey Ollie,

the question is, what is it you really want, Optic or Performance?

if it is for the Optic, I would recommend using Lowering Spring from e.g. H&R, Eibach, KW, etc.

if it is for more performance, you have also lots of choices if you want 30mm lower, e.g. from KW Variant3, you will be able to do everything you want, Softer/Harder and Height.

another option from Gert for the 3.4L is the Bilstein PSS9.

or even cheaper option maybe to change back tires from 295/30 to 285/30 might fool the vision and feeling.
