I bought the car with 20/19 and lowered with Eibach springs. Now it's time for new tires and I'm considering going back to 19/18 because I'm not pleased with the ultra low profile. I drive nearly 1,000 miles per week and don't feel like spending that kind of money once or twice a year for "dub" bragging rights. This also gives me a chance to replace the cheesy looking aftermarket rims I have now with something more to my taste. I apologize to purists, but do not care for the stock rims.

Right now I'm considering Foose rims and Dunlop Sport Maxx TTs. I do not race but have been known to goose the car for short distances on the freeway. Are there any special considerations (other than speedometer calibration) involved in making this switch?

Thanks.

 

The biggest thing to keep in mind is overall stock wheel height. Also, the offset needs to be very near the OEM rims.

You can download the spreadsheet I have here. This is from the Crossfire Documentation Collection. It has the OEM sizes calculated out and my set up sizes entered. Just enter the sizes and offsets you want to use and see the differences without breaking out the calculator!

 

No speedo calibration. The rolling circumfrence will stay the same as stock. (if you pick the right tire size)
Ensure you pick a rim with the correct offset and staggered like OEM.

 

The importance of weight is often overlooked but the noticable differance in acceleration will never be overlooked once it's there.

I have the same issue w/ 18/20 dub's
I think 18/19 is just right

Maybe grab some SLS wheels??

Yea right...
