Made a total impulse buy... Probably one of the last sets of OEM GPW side strakes left. These are discontinued in GPW so I jumped on them and probably paid way too much. Upon them getting here, I didn't want to install them. They've been sitting in the Honda box inside my closet for the better part of four months now...
I also ordered a set of Spoon subframe rigid collars. Installed in an hour or so at work. The whole process was pretty painless after you figure out exactly what it is you need to do.
After the install and an alignment, the car felt awesome! Pretty much everything they advertised was the outcome.
After subframe collar install/alignment:
The final piece to the suspension puzzle was to get the car corner balanced so I could really see what I had put together. My friend works at a NASCAR race shop, so he invited me over to corner balance the car myself on his scales.
The S2000 BAAAAAAAAARELY fit on the existing machines, but it fit. The numbers in green show the weights across the four corners and the number in the bottle middle is the total weight of the car. We preloaded the driver's area with about 220lbs (a little more than I weigh, but that was the best we could do with the resources available) to simulate me sitting in the car. When it was all said and done, the weights with me actually in the car were really close (within 5lbs at each wheel) versus having the sandbags simulating me sitting in the car. It was done with 1/2 tank of gas to give a wider range of error versus having a full tank of gas or no gas. Top down of course, because that's the only way I roll. I wanted to raise the front of the car a bit and we actually ended up at 1" lower than factory height by the end, which is perfect. There is a 1/16" negative rake as well. Hopefully as I drive more, I can judge if adjustments need to be made.
With simulated driver:
That's damn close on both for not adding any weight!!
Afterwards, I drove home, re-preloaded all of the control arm bushings, and aligned the car to factory specification. The car feels AMAZING.
Also, Honda lists a 2004 S2000 @ 2809lbs. Mine weighed in @ 2701 without driver. That means that between the new wheels, brakes, and coilovers my car has lost over 60lbs. We can assume that since it was at 1/2 tank of fuel, and one gallon of gas weighs 6lbs, that ~36lbs of gas (call it 40lbs even) should be subtracted from Honda's listed weight. So from 2769 to 2701, that's pretty substantial weight savings... and all of it is unsprung mass lost.
