hmmm.. not sure you know what kind of surface I am running on. Think of concrete but with a sheet of ice.

 

Has anyone tracked these (i.e., not autox) yet? Curious for a comparison to RS3.

 

I had a similar experience in that the car felt better without a rear bar than with the OEM on our local lots, however, the car feels great with a Miata bar. It's a cheap experiment, especially if someone has a stock NC bar locally.

 

Don't know if it's the same as you're describing, but at the limit I found that they felt like they were skipping across the surface, or losing and regaining grip several times a second. The sensations I was hearing and feeling through the steering wheel would be indicative of gross overdriving on any other tire, but with the Rivals just seemed to be the way they behaved when pushed hard.

We were running pretty low pressures (32 psi), which may have contributed to their strange behavior.

 

That's similar to what I experienced. The at seemed to just push off line once you went over the limit.

Here's my shitty ass run from the weekend. All over the rev limit and the car is a lot looser in the video then I remember when driving it. Haha maybe I should take that rebound back out of the front.

Edit: just went and took 3 clicks of rebound out of the front and the car feels much more planted on corner exit.

 

I ended up settling on 2psi less than my R-S3's. I might up the rear pressures for the next event to see if it takes some of the push out of the car.... then again, I am on a small sealed asphalt lot, so it might be just fine on a bigger more grippier venue.

 

Yeah, that's a good synopsis actually. Wayy different than a Star Spec or R1R. I am not sure what pressure Rad was running.

 

Haha, yeah I feel what you guys are saying, and in my own experience, taking the rear bar off on an STR s2000 works great at this site. Mr Lugod, I also get what you mean and concur; running more rear bar to counter the push-in-to-twitch/loose condition (really just solving a balance issue) is a great tuning solution in many conventional venues where you have a more or less flat track surface. However at this site in NJ, mechanical compliance on what is an EXTREMELY a-typical track surface in terms of surface undulation (the videos don't do it justice) definitely tames the rear end over bumps and otherwise greatly improves corner exit traction. I believe many if not all of these cars have the stock LSD's, so keeping that inside rear loaded a majority of the time is also at a premium, vs. having a magic clutch-type LSD OS-Giken which keeps working regardless of how many wheels are tracking on the pavement.

 

I'm liking all the reviews so far, but damn those tires are ugly! lol!

I plan on letting all you fast guys figure out which of the new tires is the best this year and then purchase them for the 2014 season.

 

Yeah, that's a good synopsis actually. Wayy different than a Star Spec or R1R. I am not sure what pressure Rad was running.
