I found that these cars are very sensitive to toe adjustments. Maybe try 1/4in toe in or so, that made my 01 on stock suspension with 225-255 dunlops tail a lot more settled

 

My 02 on the subject...

The weight claims vary quite a bit on the net. The range of readings between highly accurate (claimed) scales is broad and very inconsistent in my experience. I took interest in this topic when prepping my CR back in '08. I used the 2980 number because it was on the scales at HPT during the '08 National Championships and many different S2000s (all heavier) were on it including the early AP1s. They are also very similar to the scales/balance/align rack I have my car adjusted on. Last year on the same scales, my car (same prep and fluid levels) was 30 lbs off, so i don't give the weights much credit unless a variety of cars weighed in the same day on the same scale. For example, my car (always same prep) has weighed anywhere from 25xx to upper 2800s on these reliable scales. The 2004 weights from Nationals at Forbes are also controversial IMO as some of those car weighed differently on the scales at HPT.

I'm willing to weigh my car with other S2000s to provide a reliable reference point if someone can organize it. Unless someone else has done this, realize all S2000s will be close (well within driver error) with equal prep.

I may be able to organize this at nationals, if anyone is interested. I know someone with scales.

 

FYI, according to Honda with the hardtop removed, CRs with and without A/C are roughly 46lbs and 90lbs lighter respectively than a regular AP2.

 

I posted a DRAFT STR FAQ outline for comment at the link below.

addendum - Part of the CR weight loss has to do with the lack of spare tire. With the trunk empty, this margin decreases.

 

I just ran my first STR event yesterday. My last car was an STS classed RSX-S which I campaigned at regional events for 3 years before moving to the S2K. Currently, I am on a 100% stock setup in an 06 S2K. The course was very short (FTD was in the 36's - a CR running B-Stock), and a lot of fun. I know the others in my group are more set up than stock but as the car is new to me I'm learning its weaknesses first hand before upgrading anything. I don’t have the actual results in front of me as they haven’t been posted yet but they were what you'd expect. I came in 5th place after 2 S2Ks and a duel driver 08-09 Miata. My time was actually decent (40.99) compared to the class leader (38.5) considering my setup and experience with this car.

The first thing I noticed about the stock S2K is the car has a tendency to push before over steering. This was easily noticed in the hairpin turn on the course I ran yesterday and explains why you all talk about the sway bar being a must.

I'm planning to pick up a used Saner bar and get a B-Stock alignment after exploring the stock configuration for few more events.

Let me know if I'm on the right path or any recommendations would be appreciated.

Thanks!

 

^^^ yea, AP2's especially 06+ do have a tendency to push. Good luck with everything.

 

I'm not aware of any controversy. All of the BS cars were weighed at the same time, and all of the AS cars were weighed at the same time. I do know there was some commentary at one of the HPT Nationals because everyone's cars scaled twenty or so pounds heavier than they weighed elsewhere.

I think the takeaway is that weights generally aren't comparable between different sets of scales. I'm learning this the hard way in road racing, where I try to stay within ten pounds of my class' minimum weight, but different tracks' scales vary by twenty-plus pounds. I've never seen three hundred pound differences between scales like Marc has, though.
