18 inch wheels on cabriolet

I bought a cab last October with 18" wheels and it's been great fun. It's been on the track three or four times and is fine there and is only bad on hte really rutted country lanes around my house where there are reasonably sized holes. On anything but those roads it is fine. Have not tried it with 17 inch wheels so can't compare but there isn't too much scuttle shake. Live in the Henley/Reading area if you want to come and try it out.

We have 18" hollow spokes factory fitted to our Cab, and they are fine... In fact it was because we have factory fitted 18" Maurice ended up doing more investigation and revised the FAQ.
If you are looking at a car which has had 18s fitted at a later date, make sure the VIN on the car is suitable to accept them, and the steering brace (NOT strut brace) has been fitted.. I also suggest they are quality wheels and as light as possible, if not you will suffer from the car tramlining etc..

Hi Maurice
Don't know what your thoughts are on this. Some time ago I was talking from someone who used to work for Porsche. The question of 18" wheels came up for the 993's. It was stated by said person that a lot of early customers of 993's looked to retro fit 18" wheels as at the time Porsche did not offer 18" wheels. Porsche's response was to issue a statement saying it was unsafe and they should only fit OEM wheels. Not long after 18" wheels were introduced on specific models and later as an option on other models. I am not the expert here and am only relaying what was said. It was inferred that there were no body changes whatever relating to strengthening for 18" wheels on coupe model bodies only the fitment of the brace and that subsequent lists etc were released to merely add weight to back up the original statement regarding unsuitability. I know most owners with 18" wheels have ensured that they have the steering rack brace fitted and I would be interested to know exactly what these body strengthening mods are if in fact they do exist.

Hi Maurice
Thanks for the reply. I am aware of the article in FAQ which goes into great detail but it does not answer the question of what the differences are. It just seemed strange that this unprompted remark should bring forth comments that there were no actual changes to the body structure. With the enquiring minds of our members I am surprised no one has asked this question. If fitting 1" diameter larger wheels can cause sufficent stress problems on those cars not listed on the chassis number list does this also mean that the stress transmitted through the system by firmer springs and dampers are also questionable. I am merely trying to get a clear understanding of the situation and I must admit I personally view the purported Porsche statement as sceptical. I am assuming they offered the M030 for the earlier cars and i cannot see if this were the case why the 1" larger wheels can cause a problem. But there again what do I know?
