I have the 996 Turbo-twist 9" wheels on my 928 - on all 4 corners. I run 295/45/17 Victorracers on it and it sticks like glue. But - I want to add fender flares and go wider still. This is a road and track car, and I could use the extra cornering. Here is the problem: the 295's are the widest thing I can put on a 9" rim. Anybody know where I can get some used 10" or 11" rims for my 928?

 

Carl,

Give Cory a try at <a href="http://www.planet9eleven.com" target="_blank">www.planet9eleven.com</a>
or: 1-405-260-2911

I bought a set of 17s from him.
He has a good selection and is easy to deal with.

BTW, I think I saw a set of 10"+ wheels in his shop recently.

Give him a call.

Scott

 

I agree! I bought 2 sets of wheels from Cory. That is where I will get mine from now on. Be careful, his 911s are so nice it may make you want to switch models...or add one to your to your collection ;-) He is a great guy!

 

I think there is a note in the DEVEK catalog about custom wheels. They also have a kit that disables the Weissach effect of the rear axle for tires over 275 size.

Giving them a call certainly could not hurt. The number is 650-592-5287.

 

Hi Nicole I bought a pinning kit for the rear axle, I must say I dont disagree with the principle that is being applied but, what is required to be done is to drill into a suspension part that is very difficult to preform accuratly. I think drilling into an aluminium suspension component without fully knowing where your drilling is dangerous. Also I would only do this if you could ascertain that there is enough meat left in the piece being drilled.

Further more if that was established I would champher the holes that were drilled to stop future cracks occurring. The better way to do this is to have a different bush made that is basically rigid this will achieve the say thing safely. All the best.

does anybody on here have experience with disabling the weissach axle? if so id really like to hear from you, what did you do and was it succesful?

i am sure that mine is not assisting with higher speed stability since the addition of stickier rubber on the rear. i am looking for advice on what and how to modify the award winning 70's design!

 

Quick Carl:
I'm sorry to tell you, but tires that are 295mm wide are too wide to be safe on 9" wide rims. They extend over the edge of the rim by more than an inch on each side. That's WAY over what is considered safe.

To use DEVEK's rule of thumb, your tire to wheel ratio is 0.775. That's considerably less than their 0.85 minimum. I suggest you get 10" wheels just for those tires. If you plan on going even wider, then you'll likely need wheels that are at least 11" wide. Good luck! YMMV.

 

Carl:

What are the offsets of the wheels that you are running now?

TIA
