For me, the killer is the 100 tread wear in Mod class. I can pretty much fit in street class, but my tires put me in Unlimited. Many of us run V710s, so we'd all have to be in Unlimited even with Street class mods.

I know you said you want to encourage people to use NT-01, but are most people actually going to buy tires specifically for this event? I have my whole setup purchased and ready to roll for next year. I wouldn't purchase another set of tires just for one event. Do you intend to exclude people who compete in SCCA/NASA autocrosses and time trial events but use race tires below 100 rating?

If I wanted to run Street class, I'd put on my 255-width RT-615s and go to town. Not great for racing, but maybe good enough for a *****-out best lap as long as I do it before they get greasy, hah.

 

2-way adjustable coilovers mean rebound and compression, not how many clicks you have available...

EDIT: I'll be buying a set of tires specifically for this event no matter what class I run in. May as well be the 255 Nitto.

EDIT 2: I hope this doesn't fall on the same weekend as the NASA Nationals...

 

992gnt is correct.

Your coilovers are 1 way adjustable with 4 different settings. 2 way adjustable is compression and rebound adjustable (Eg: KW V3). Most people only run 1 way adjustable coilovers (Ohlins, TEIN, Megan, helix, etc).

 

My bad sorry for the confusion. Still the tire thing sucks for me.

 

The $1000 purse for fastest time on NT-01s tends to help motivate people to run those. Also, last year we only ran two classes, street and unlimited. The mod class is new this year. Normally anyone with an upgraded turbo or cetain tires would have automatically jumped to unlimited anyways.

Some people are not going to like the classes, but it is a balancing act between the most amount of people likeing them (including sponsors) and being fair. I recognize that no matter how we set them up, some people won't come. Keep in mind there is also a DE for as many as 80-100 cars on the 22nd and 60 on the 23. So if you dont want to compete but stll want to have fun, we have this, and it will be cheaper.

 

I'm just saying that V710s are the most common tire used nowadays, and you have the same treadwear minimum for both street and mod. It doesn't make sense for MOD-level cars to only use 100 treadwear tires. That's like using a side-mount intercooler on a GT35R. I don't have an upgraded turbo or anything drastic, but I have 285-width V710s. My mods will be equal to Street class, but my tires will put me in unlimited. I can see forcing NT-01s for the NT-01 class, but I don't understand forcing NT-01s for the mod class when there is already an NT-01 class.

 

fyi - v710's are not the most common tires around here.

100 tread wear tires such as RA-1's & nt01's are MUCH more common.

I understand you want to make it fair for people to run Nitos since they are sponsoring the whole thing, but who in their right mind is going to go out and spend $1,000 on tires to hopefully win it back?

Can you maybe increase the width limit to 275 in the street class? because if thats the case I can fit in that class perfectly and considering thats what Im set up for on Redline series it would be awsome.

 

Nils, i would consider RA-1s the most common overall, but not for those trying to win a race. As for NT-01s, I have yet to see a car with those, so maybe it's a regional thing. In my region, I see either V710s or RA-1s, and the RA-1s are not competitive. This is mainly auto-x, though, because our road racing competition is light due to being a new NASA region, so I don't see as many competition TT and race cars as you.

 

well, the RA-1's is a Dot-R radial & the v710's is a Dot-R slick.. right? I also thought the v710 were designed more for autocross than road racing/tracking. Thye probably heat up real quick....

so you want them to allow Dot-R slicks in the modified class? that would allow Hoosier R6's too.. which would smoke the v710's IMO.... kinda opening a can of worms here... & i like the fact that modified gets limited to a 100 tread wear rating.

Warrtalon: Kumho V710s are primarily designed for auto-x and not really for track use, like the Hoosier A6s. There are other R-comp tires that are designed and used for road racing that are a little harder compound, take a longer time to warm up and last a lot longer. As Nils has mentioned lots of track junkies use Toyo RA1s and Nitto NT-01 for track days ... from what I hear they are very similar in performance and longevity.

Haha maybe there should be a stock class with street tires .... you guys need quit complaining about where your car falls and either mod up or de-mod to fall into a class ...

 

You had one and few came even fewer competed (one third of the unlimited field came from the west coast)...(sorry the 2200 fuel bill still cranks me to show up to race the "hot east coast Evos" and nobody showed...(GSC excluded) even AMS haulled from Chi-town (same haul to SMMP)

 

The Spec NT-01 prize is not really a class. It is a prize for the fastest car on NT-01s that already is entered in street or mod. So you can actually win that and the class you are in. The NT01 is an incredibly capable tire especially when down to 3/32s. Robi ran times within a second or two of the AMS car (running 295 hoosiers) with a set of 275 NT-01s on 24lb wheels last year. So this is hardly a major handicap.

Some people will not want to buy new tires, some will. Some already have them. And being the race is 10 months off, many people will have bought new tires several times over giving them the option to buy these next time they need new tires. Since most people run RA1s, its not any kind of stretch that they would switch to NT-01s

 

The V710's hit optimum by the end of your outlap. Better click off your best time on your first flying lap.... lap 2 will suffer and forget about lap 3.

This info has come from many evo owners that time trial with that tire. They all changed over to R6's V710 is a good autoXtire.

CharlesJ: is there a Spec NT-01 cash prize for each class? Meaning one for Street, one for Mod and one for Unlimited? Because if it is all combined then the unlimited cars on NT-01s will definately take the prize. Catch my drift?
