Yep ok thanks. If I don't sell the wheels with the car or separate ill keep them for the ute and try some fatter tyres on them as you said. I don't really want to run stretched or too low as I've been there done that plenty of times and the car will be used to tow every now and then and also look to add a bit more power to it (I'm not sure how it will handle). I guess I'm looking for the happy medium which is always hard lol.
Appreciate your help noticed you give a lot of advice on here (read nearly every topic and page in the ute section). I'll continue to do some research
Still have to decide on the N/A or T XR6 also, worried about the driveline on the T for towing but I guess sub 5.5 alloy boat won't be too heavy with the HD 2300kg tow kit.
