Well, I took my F45 out of the PC and installed Bilstein Sport shocks combined with Hotchkis sway bars and VBP front spring @ 745lbs and VBP rear spring @ 1050lbs. I autoX my car as well as take 3-4,000 mile long road trips each year - this is not my daily driver - and the ride comfort is far better than the OEM suspension was.

Wheel hop is typically related to your tires so I would start there. I am running Nitto Invo on all 4 wheels and have no hop problems. I ditched the run flats.

All depends on how you use the car and what your needs are. I am swapping out the Hotchklis bars for a set of Pfadt street bars next weekend to get better cornering capability.

The VBP springs are a lot better built than the OEM ones and their lb rates are actually higher. An 840 or 860 may be a good fit for drags but I would call them and discuss your application. They have knowledgable folks and offer a money back guarantee.

I would like to know how pleased you are with the nitto's. Do you have better traction (less wheelspin) with these tires? I am considering replacing my stock tires on my 2008 C6 for a pair with better traction & am wondering if it is worth the expense and the loss of peace of mind that the runflats give as related to potential flat tires.
Do you tote a tire repair kit and a jack or are you just hoping to not get any flats?
