Reverse lip rims?; 19" and wet weather


Recommended Posts

I've an 07 Boxster S w/ OEM 18" rims. I want new rims, probably 19" Carrera Sport. I've seen discussions of issues w/ reverse lip rims, but I'm not sure I understand exactly what this means. Can the board help me with that? I assume it's not found on the Carrea Sport or SportDesign rims offered by Porsche. Correct?

Some report big problems with balance issues when a reverse lip rim fails to shed rainwater. My car is driven in the rain, quickly, so I can't have this issue. Also, it appears that reverse lip imbalance is a problem in some (all?) models made by HRE, DPE and iForged. True?

Finally, some discussions have suggested that 19" setups don't handle heavy rain as well as 18." I'm dubious on this (assuming wet weather tires), but am concerned because I want very good rain traction -- figuiring I'll push the car's limits in rain much more than I'll push its limits on dry pavement. No snow or ice, just rain.

Best

Can't help you with the reverse lip issue, but I run 19" Carrera Classics with Michelin Pilot Sports on my 08 S and haven't noticed any unusual lack of traction on wet roads or balance issues under wet conditions either. It will definitely come loose if I get on it though and I definitely don't drive with them on snow or ice either! I have in the past and they are a bear to handle.
