| On the cast wheels I'm seeing cracks all the way through the metal from the edge of the wheel (tire bead) traveling straight across perpendicular to the radius. No damage to outside of rim. |

120mm vs 120.65mm
I've thought about it a bunch and tried running a 19" BBS LM last year in BMW bolt pattern. I would've stuck with them but they were only 9" wide all around. 
CCWs are nice but 16" wheels are so 1985.

Weak wheel.

So tell me how much traction you have with those rubber bands? 
Seriously though, I bought some drag springs and I think I'm in the quest for a hard launching car. Need some fat and grabby drag radials. Big diameter wheels don't let me do that. |

No argument here, just telling you potholes and curbs are what are doing it.

My 19s are significantly taller than factory 16s, running a 35% aspect ratio I get over a 4" sidewall. Factory sized 16s get a hair over 3/4" more than that. Plus I have much more width and length being a taller tire. Besides, I couldn't care less about drag racing, I have all the lateral grip I need at this stage of my skill level.  |
