Re: 2018 TIRE INDEX ADJUSTMENTS

We don't have a huge amount of people using >200TW tires, and even fewer people actively testing the differences between these tires. Using your numbers, someone...

Re: 2018 TIRE INDEX ADJUSTMENTS

i think the power index looks good, Ed. the proposed tire index doesn't seem to map to the real-world performance data, or to distinct UTQG rating ranges (TW 200 - 204???). The Parsons and I had recommended the following, which has buy-in from a few members: > 301 TW : 0.98 300 - 201 TW : 1.00 200 -...

Re: 2018 TIRE INDEX ADJUSTMENTS

Based on real-world data and feedback from club members: < 100TW tires - 1.02 Current-gen 200TW and 100TW R-comps - 1.00 Last-gen 200TW - 0.98 > 200 TW tires (all) - 0.96 The current "cheater 200TW" are the benchmark (Rival S, RE71R, 595RSRR, RS4, SUR4G), since that's what the vast majority of the f...

Other members voiced this desire on the facebook post. Not because we're overly competitive, but because we desire...

2018 TIRE INDEX ADJUSTMENTS

All, Tire technology and performance has changed significantly from when the CDC tire index was last updated. Given similar car prep and driver talent, a driver that shows up on Rival S or RE-71R is pretty much guaranteed to beat someone showing up on "last generation" autocross tires. To level the ...

Frank says "framed portrait".

BRAND NEW Maxxis RC-1 slicks 205/50/15

I have a set of four (4) BRAND NEW IN BOX Maxxis RC-1 slick racing tires. They are 205/50/15, 100 treadwear. These are r compound tires and are still DOT stamped for street legality. These are very similar in performance to the Nitto NT-01, but with better/stiffer sidewalls. They grip well in damp /...

Re: bump stop modification? (NC Miata/RX8)

total load transfer is a function of the CG and the track width, no other suspension related factors. so if you increase the front and rear swaybar stiffness proportionally, you are not increasing weight transfer at any wheel, and the vehicle stays flatter. since total load transfer is not affected ...

Re: bump stop modification? (NC Miata/RX8)

Swaybars increase weight transfer at the end they are working at, which decreases weight transfer at the other end. A stiffer rear bar actually causes the inside rear tire to be pulled up or jacked up. So you're actually loading the outside tire MORE heavily with a stiffer swaybar, but you get less ...

Re: bump stop modification? (NC Miata/RX8)

Realize this is a dead thread... but what about swapping the front and rear bump stops? Then you have softer bump stops up front and stiffer ones in the rear.

bump for excellent tires that wear like iron, come up to temp quickly, don't overheat, and have good heat cycle life.

Re: 2015 Track Season

I'd recommend trying a "hyperdrive" at a NASA event.

"Hyperdrives" are generally available at most...

Ignition timing was way off (retarded), but the car did pretty well for being stock (and overweight...) plus FM swaybars.
