To be honest, I dont really care much about ride comfort... I have other cars for that

The MPGs is what really motivates me on long distances!
I just checked the prices on the HDs though, and it looks like a front/rear set will cost about $644 (tirerack.com). Wouldnt it make more sense to spend the extra few hundred and get the coilovers for full adjustability? Aside from ride comfort, are there any other negatives?
Also, if someone can comment on the camber and rubbing points above I would really appreciate it. Thanks!
