I always thought that was ridiculous, since both are "ST" classes. SCCA needs to update the rulebook on that.intercoolers arent allowed in STU either. Only STH allows them afaik which the R doesnt get classed to.
You have this exactly right.I think it has to do with STH being an all turbo car class and STU is not. All you can do is write letters in asking for it to be changed.
How do you feel with the R in DS? Is it competitive or too competitive?Got some interesting running today, though ended the day in kind of a down note....
Ran some tests with the pedal dance vs +R and Hold method of disabling VSC. Small local lot, asphalt, low 60s and damp to wet. Running on the same set of RE71Rs from nats but flipped before this event. Was hoping at least it was gonna be dry but unfortunately not the case. But I think the wet running actually helped showcasing what was happening. Knowing it was gonna be wet I put the Karcepts to full soft and dropped pressure to about 30/28. Big takeaway is the car definitely is doing some weird thing with the AHA enabled in the +R and hold method. The course was tight with some interesting decreasing radius corner entry and some really tight slalom entry. If you try to trail brake or doing some mid corner adjustment on the brake and the car will try to "help" and it generates a ton of yaw and you are basically drifting. Only way to avoid it is basically to straighten the wheel out then brake. Doing the pedal dance basically eliminates this behavior. The car is still pretty free but it doesn't do it as unnaturally. This surface is pretty low grip to start with and the wet doesn't help so it probably made the behavior differences much more pronounce, I feel like if it were dry concrete and warm day you are gonna be much closer to the saturation point of tire limit that the effect might not be as obvious. Also due to the condition and course I really can't draw any meaningful comparison if the shock mode differences(+R v Sport) doing the 2 method counts for anything, I think the AHA behavior dominates this experiment today. I kinda prefer the pedal dance under this condition as the car to me is more predictable. Ken however noted he thinks the car has worse power down traction issue(more inside wheel spin) on corner exit when we are in the pedal dance mode vs +R and Hold. The previous explanation on AHA does say that it works on both axle so I think there is some merit to maybe AHA is also trying to enhance the LSD action. Our best time of the day was set in pedal dance mode but it was really not a true A-B-A test. I do think if you drive the car in one mode vs the other constantly you may arrive at very different setup(bar/alignment) as I feel like you might go more aggressive(on dry at least) with pedal dance, because the car isn't trying to artificially loosen itself up. And certainly lends merit to the more exaggerated brake wear.
We ended up 7th/8th on Pax out of 141 despite the fact that the entire first heat ran in the dry condition and we ran in the 4th heat when it was definitely not dry...so the car was doing ok....
Comes time to pack up and go home though I got 2 more lugnuts seized on the wheel studs. I had one did this at Nats on Thursday Evening and was able to replace it with parts from O'Reily's...being wet and disgusting and this time on a front I just jammed them back on and torqued the other 3 so I can drive the car to a friend's and borrowed another car. Ordering a set of replacement studs and new lugnuts now....At least per the factory service manual, you don't need to remove the hubs to replace the lugnuts on the Type R at all...on either axle...
Interesting! In the wet I never run R mode anyway - suspension too stiff and everything's a little too twitchy with the steering / throttle mapping. The only time I've pedal danced my Type R is in the wet. I'd be really interested in a concrete / warm / dry A-B-A test on this.Got some interesting running today, though ended the day in kind of a down note....

I was hoping one of the folks down south could help us northerners outYeah maybe next season, not much to do now in Michigan...lol
