Top 5 mods for a standard 968

[paulf968]

My standard Coupe (not Sport or Club Sport, no MO30) was found to be a bit slow compared to other cars on a recent trackday. I promise you it was not the driver!!

Question: What would be the top 5 things you would do to such a car to make it perform better on a track day. I do not want to jump into expensive mods, getting more speed is nice but it has to be balanced with the cost. Assume that I am running on Optimax and I have already taken as much loose stuff like carpets, spare wheel etc out of the car.

I have only tried one quick and zero cost mod -- took out the air filter completely for a few laps. May seem mad but the air box is quite high up and there is plenty of grills etc in the intake area. Seemed to breath well and there was a sense that the engine was working harder.

I read somewhere that a performance filter was worth at least +10 bhp. So might customise an open mesh gauze filter to replace the standard paper jobbie on track days.

If that first mod makes sense what would you do next? mapping/chipping? suspension/anti-roll bars? brakes? LSD? I really have got no idea.

968 engines are notoriously difficult to get more power out of, as they were pretty thoroughly designed by those nice Porshce chappies. There is a reported issue with K&N type filters causing oil build up on the air metering system, which is why I haven't fitted one to my car. Besides, it has a fairly large volume filter element already.

Most fruitful work probably is in the area of suspension, brakes and tyres.

I too have a standard coupe, and if wanted more track speed I would start by lowering it. Then I'd add M030 anti-roll bars, lighter, larger wheels, and better tyres. Lastly I would look at upgrading the brakes, maybe no more than better pads to start with. In terms of lap seconds shaved per £ spent, this lot will pay more dividends than attempting to fiddle with the engine.

Welcome to the forum Euan - what kept you?[]

legaleagleboy,
I can't emphasise enough Eauns last point. The most cost effective, and usually least expensive way to make your car go faster is to get some instruction. Either at a track day with instructor available, or take lessons at a race school near you.
There are also some recent threads on the forum at the moment discussing private, or small group tuition. Maybe an even more effective purchase.

Good luck! Have fun!

Euan, welcome on board, and glad that my few words in PP have had the desired effect.

Euan and Mark, quite agree, instruction AND practice.

Page 72 in the latest 911 & Porsche World mag advertises a 968 Supercharger kit for £4750 (excluding VAT and fitting!!) from Ninemeister, but it does deliver 350bhp.

Of course you've then got to think about suspension and brakes to handle the power, so the phrase "prohibitively expensive" comes to mind.
