Worthwhile 964 modifications/upgrades ?

Thanks for all your replies so far - keep them coming ...

Cup Pipe (I prefer the sound to the G pipe)

It seems as though there are 2 distinct groups - those that prefer a G-pipe & those who prefer the Cup pipe ...

Recaros (Andy you're a slim chap you could try the SPG )

Already have some (standard width) SPG's but they are a tight fit - have some PP's too ...

... and his and hers cup holders from TP81, but that is obvious!

- no cup holders here Wayne !

Even though they look beautifully designed/engineered - & I am a lover of good coffee - I just don't get the whole 'thing' ....


Thanks for the clutch lever mod info - I'll keep that filed away for future reference.

Maybe add a nice carbon front strut brace too which is cheap ...

- interesting Jason.

Do you think they offer any real benefit on a road car ?

Hmmmm maybe not a lot on the road.

I always used my 964 on road and track and found it made the front a little stiffer with better turn in.

With the state of the roads now (they are horrendous around us) maybe just see how you get on without one first....

I had a strut brace on my car and removed it for half a day at Spa. Was definitely noticeable on track.

Andy there are LOTS of articles here on modified 964s....

Thanks Jason - unfortunately clicking on any of the links in that thread just takes me to a page stating:

Andy, if you’re looking to improve the 964 you should ask Tony Hatter, he did it many years ago and to very good effect.

Thats a shame - maybe PM blackbetty in the first post and ask if they are being hosted elsewhere or if the site is just down as it had lots of cars for ideas etc....

All that modding stuff for performance and no mention of tyre choice?

Pointless bolting all that jewelry on and keeping the tyres, tyres are your connection to the road and should be on those lists, and there are several to consider.

......Wheels and tyre choice are important and a fast road set up .

Indeed, missed your comments, but all this mech stuff will be for little if the tyres can't deal with delivering what is expected.

These are all well-known modifications with many 964 owners utilising various combinations over many 1000's miles.

None of these modifications are aimed at producing big increases in power - more to maximise the capabilities of the 'chassis' & to reduce weight wherever possible (within reason).

Tyre choice is a long way off & will depend on what size of wheel the car is fitted with (eg 17in or 18in) but it will be purely a road car.

Speaking of which, what's the general consensus regarding 17in vs 18in wheels ?

I do like the look of the original 17in Cup 1 wheels - but am also a fan of the Eta Beta Krone/BBS look & think they're only available in 18in diameter ...

Andy .. read steves posts here ( from where he posts photo and running update) .. he disccuses wheel size purely from a driving perspective

I have built a number of 964s in the past and found that fitting
993RS front uprights ( commonly referred to as GT2 uprights) and
steering arms gives a big improvement in steering feel and allows
fitment of any 993 (including turbo) radial mounted calipers. I'm
not 100% they are still available from Porsche though.
Brakes are important though as I think the 964 brakes are not
really up to the job for fast driving.
The above plus, good suspension and loosing weight gives real
benefits.

Regards.
