I'm looking to widen cast porsche 15x7 wheels to 15x9 in order to take advantage of the (relatively) new Hooser 275/35/15 tires. Car is 2500 lb 944 cup car with a stock (140 hp) motor. Additional rubber aside, the gearing advantage over my current setup is almost 11%
Porsche did not make a 15x9 wheel, so widening the stock wheels are the only way to make this work. Some in the series are already doing this, but I'm looking for some sanity check...
I plan on using weldcrafters out of Michigan to do the work, as they have have gotten rave reviews on this board and elsewhere.
Question is - there are the usual horror stories people hearing about welds breaking, weaking original material, etc. and accidents all over the internet
1) Are people racing on these wheels?
2) Do people know of any failures that can be directly attributable to weld failures? Or are these essentially urban legends at this point in the game....
A fairly exhaustive internet search hasn't yielded up much information as to actual weld failures.
My personal hypothesis is that OEM wheels feel on a regular basis during track use - seen on many OEM porsche wheels over the years - and that a quality widening jobs represents no increased risk above running what are now 20+ year old OE wheels.
Thoughts/experiences are welcomed. Please no soapboxes.
