I know. I'm so inadequate. Alas.

 

If you lower the car too much, you run out of adjustment and can't get a decent alignment. Not really an issue with a modest drop; I'm dropped an inch in back and a tiny bit more than an inch in the front, and have adjustment to spare. There are limits though, so unless you plan to move some suspension mounting points around or don't care about handling you will want to limit the amount of drop.

 

Ah I see. I was thinking about an inch as well for my car. Now would you say with good suspension the inch lower would help keep the weight lower therefore increase grip overall?

Anyways thanks your posts have been most helpful!

 

I made a mistake when we lowered my car, and changed the alignment at the same time, so I can't really be sure, but going from the OEM springs to an Eibach Pro Kit and from US Alignment to UK alignment may have netted a small gain in grip. However, since it was on the order of 0.03 G's it's within the range of measurement error. I average together a number of tests to get better accuracy, but it's still hard to be certain. The lower CG decreases total weight transfer, and even though the roll center drops more than the CG, a lower roll center only increases the roll couple; It cancels out some or all of the reduction in body roll you'd see due to the lower CG, but you still get less total weight transfer, so a small increase in grip actually makes sense (assuming you get the alignment sorted out properly).

In any event, it is certianly not enough to notice. For big gains in grip you have to go with aftermarket tires.
Ask CKit about his Pilot Sport Cups.

If you upgrade and sell your car, it'll end up in a guardrail, ditch, curb, etc, etc, etc. It's our duty to preserve the remaining MY02's on the market

I'd love to go with some crazy aggressive tire, and maybe in the spring I will. I do (like many of us) have to consider wet grip as well though since it is my primary and sole vehicle. I live 5 blocks from my office, however, and have Blizzaks for the winter.

How do the Cups do in the wet?

 

When I sell the S2000, I think I'll sell it for a few thousand under market and take applications to weed out the noobs.



Or maybe I'll get around to installing the Racelogic Traction Control...

Or maybe I'll turn it into a gutted track car (if I get a bigger driveway).

I don't know how the Cups do in the wet. I'm not brave enough to try them. Don't think they'd do very well, they're barely more than slicks with a few grooves in them.

This is the first year that I'm storing the S2000 during the Winter, so I used the Winter rims to mount the Sport Cups. I have S02s for Spring / Fall. This past year, I had fresh S02s and drove in the rain to WTD. Drove in the rain at the Dragon and it snowed on the last day. They did fine. The only time I've had a problem was when they were on their last few mm of tread.

If it was my only car I'd probably go with RE-01Rs and Blizzaks (summer / winter) combo.
