RX-8 'Stock' Wheel/Tire/Shock Improvements & Specs

Post by tottoatol »

Using G-Tech Pro meter for measurement.
Right off the Showroom floor (6-Spd/Sport Suspension Package/225-45 Bridgestones): .93G's (Left or Right)
Added BFG g-Force KDW-2's (225/45): .96G's (but just ate up the right front)
Added Tokico D-Specs (full firm) & SSR COMP-H/Kuhmo MX's: 1.01G's
Added Enkei RPF1 (18x9.5's) & Azeni 615RT's (275/35): 1.1G's
----
I suspect putting 245/40 R-Comp's on the SSR's she could grab 1.25.
Thanks Brian for all the ideas/suggestions.
Aloha,
Tom

RX-8 numbers

Stephen, I pulled them off the g-Tech Pro meter I have. If we ran in opposite heats...and not against each other...we could set it up in your car. Maybe I'll start running B-Stock again (get some R compunds) ...it's fun competing, but I just can't quite catch you. :-)
ALoha...

RX8 G Specs

Post by tottoatol »

OK...finally got some R-40's. The new BFG R1's and here are some early numbers (first event, 4 runs):
Mounted the 245-40 R1's on the 18x8.5 SSR Comp H's I got from Brian with some Kuhmo MX's. The Tokico D-Specs were all set on 1/2 turn short of full hard. Other than the new HP Plus pads I got from Brian, everything else is from the showroom. Actually this didn't even sit on the showroom, it was the 3rd RX8 to touch Hawaii soil/lava and picked it up after a dealer prep. But I digress...
The best G on the new tires was 1.2. A full .1 pickup from the 275-35 Azeni's on the same car setup except the tires. The times on a nominal 30 second course were 30.1 with the R1's (not showing any wear) and 31.6 with the Azeni's. I suspect the car will do better than that as the driver learns and the tires break-in some. Tire Rack has an article comparing the R1's to the A6's and the R1's did better on the track and in the wear department.

hey tom, your ssr's are 8.5 wide? if this is true then they actually arent legal in BS, wheels must be of stock dimensions (18x8) and offset must be +/- .25". if not, its okay i wont tell :p

how is your car?

Tires, Shocks, Suspension & G's...oh my

Post by tottoatol »

Stephen,
UH....Typo....I was thinking Enkei's (9.5) & SSR's (8.0) at same time and typed 8.5. That's my story and I'm sticking with it. :-)
Brian can confirm that the SSR's are OK for BS. :-)

Car's ready for pickup! Gotz to head down there now and pickup.
Mazda North America has not returned my email or calls on whether they'll pickup the tab...being just 6 days out of warranty. Of course, I should have taken the R1's off before they took it in for service. :-)
I'm thinking with a 'new' front end under me....1.25 G's? :-)))
Later....

Stock class requires stock width...you can change the offset up to 1/4 inch. So, 8 inch SSRs for stock class.
