Hi guys i have recently purchased a nice carerra 2 Targa and wanted some advice on changing the roll bar from black to stainless finish has any one done it and do you have any advice please ? also do you know if the bar cove from an earlier car with the 3 groves on the side will fit a 964 ?
The car seems to sit a bit high at the front if i wanted to lower it all round do you know if i can just change the springs or do i have to change the shocks too.
many thanks

Colin
 
Hi Colin. Hope you've been enjoying your Targa since you bought it. Perhaps, you could post a larger pic or three when you get chance and tell us a bit more about it.

With regard to your question about front ride height and changing springs, this is one of the most oft debated topics around the various Porsche / 964 forums (see the Links thread further up on the 964 Forum), including this thread:
https://rennlist.com/forums/964-forum/85136-lowering-964-a.html

The 964 model has been one of the most popular models for modifications and I'm sure you can achieve the conversion from black-to-silver. Again, if you haven't already, it's worth checking across several forums until you find a posting that addresses your questions.

Cheers,

Paul

 
When we had the annual meetup at Brands Hatch 3 years ago, there was a display of old cars that had been brought back to life as part of a national competition for the OPC's. One entry had a 964 Targa with a very shiny roll bar. Whether it was brushed aluminium, or simply bare metal that had been polished I can't remember. As to getting one made of stainless steel, I would think the costs would be very high as SS is quite brittle.
 
Hi guys thanks for the replies. I used paint stripper in the end and it came of well. Another question please i am changing my D9 16" alloys to some Fuchs style 17" the tyre sizes at the moment are front 205 /55 /16 rear 225 /50/16 would the best replacement for nearest size be front 205 /50 /17 and rear 225 /45/ 17 ? plus what do you think of Yokohama tyres ?
Many thanks
Colin
ps original fronts were 6" and rears 8" the 17" wheels will be 7" front and 9" rears
 
The rear tyre sizes are wrong.
The front wheels should be 7-8J wide and the rears 8-9.5J wide.
So the front tyres are correct at 205x50 or 245x 45.
The rear tyres 255x40.
There's a site very useful for working out what the effect is with different tyre sizes. You need to make sure that the offsets are about 50-55
(ET number).

The factory supplied 17" wheels are
964 front
7Jx17 ET 55
964 rear
8Jx17 ET55

He says "Fuchs" so not 17" cups
 
Fuchs were never a factory option but the wheels need to have the same basic parameters.

If you go to the site I linked in, having the factory specs is necessary to put in the 1st column, then the ones you're wanting to fit in the 2nd column. Then you can see the effect of the changes you're wanting to make. 964's have staggered wheels, wider ones at the rear.
When getting new wheels you can make sure that the change in wheel dimension and tyre size doesn't effect the speedometer too much, as it's not just speed but also the anti lock braking system that are effected.

You can't fit Fuchs from an impact bumper 911 on a 964.
 
They won't fit Colin because the offset needs to be greater than 50. Those you want only go to 40.
 
Hi David they do them in a 50 offset to so that should be okay thanks for the link to the comparison chart excellent information when you see the comparison between factory and what you want to put on it says for the rear you could probably also go 245 45 17 with a 50 offset on a 9" wheel.

thanks for the info really appreciate it hope to post some pics when its done.

FWIW I saw a 964 backdate at a show late last year......had the Foosh wheels and a beige paint job with orange graphics...very "singeresque" looked amazing, sadly Ive lost the pics I took.

Colin, all the 9" x 17" wheels have 255x40 tires. The 9x16 wheels are the 245x45 tires.
Please note the tyres are different when using on the front or rear. Look at the 8x17 wheels.
 
Im sure the 40ET wheels would fit, they really would fill the arches as a more typical ET would be 55ET, so these would be 15mm further out.

I have never seen Foosh before but you gotta love the name!

These are a more typical Fuchs look for 964 & 993

I ran the figures through a calculator and 40ET would fit.
I'm using 9.5J x 17 ET 49 and I don't have 15mm free space within the wheel arch, (more like 5mm) maybe with rolled arch lips.
Care must be taken with the width of the wheel, aiming for ET 50-55 will not present a problem.
That tool on http://www.rimsntires.com/specspro.jsp is invaluable for sorting stuff out.

Thanks guys the reason i thought about 45's instead of 40 profile tyres on the back was to make the ride a little less harsh as i have just had new Bilstein suspension all round with H&R 40mm lowering springs. But if you think it wont work i will stick to the 40's.

thanks again for all the help

Colin
 
After a couple of months the suspension will have settled and you'll find it more comfortable, or you get used to it, I'm not sure. If you are running the car at -40mm then you might encounter bump steer and have a harsher ride because the suspension is too low.
Get the suspension set up properly. I know a great guy in the Midlands who does it for £85.
