Automotive Marketplace / Cobra Suzuka Racing Seat

« on: September 23, 2019, 11:31:36 AM »

Almost new Cobra Suzuka racing seat for sale! I bought it new this August. FIA approved, HANS compatible. Used for 2 autocross events. I’m 5’11” 165lbs and have a 34” waist and I fit comfortably snug. Not squished kinda feeling but secure feeling. This is a beautiful seat and the only reason I’m selling is because I have another person wanting to codrive my car and he doesn’t fit quite as well as I do. So I’m hoping to sell this seat and get the almost exact same one except the wider “GT” version. I paid $1300 for it and looking for $1100 obo if someone is interested. Text four0three 7four1 five2one5 if interested. Thanks

General Discussion / Friend in wheelchair wants to race with us

« on: July 30, 2018, 07:48:04 PM »

My friend Landon had a unfortunate crash on his dirt bike that left him a quadriplegic several years back. After a crazy amount of determination and hard work he has been able to get his drivers licence back and has been driving with hand controls for over a year now. He was going to setup a mustang to drive but was unable to get in and out easily. He has now acquired a go kart and wants to race it with us when he gets it setup for hand controls(probably next year). He also drives a hand control side by side around our local motocross track.  I have seen articles of a guy down in the states that races autocross in a wrx with hand controls and does quite well with it. I have quickly browsed through the rules and don't really see anything on hand controls. When Landon gets his kart setup and ready to go can he come race with us? He will be more than willing to work where he can(registration or grid maybe).

Technical Talk / Wheel and tire sizes? Is wider worth the weight?

« on: January 28, 2018, 08:37:45 PM »

This year I'm looking at 2 options for wheels and tires for my 05 mustang.  I'm curious to what your guys thoughts are on tire widths and whether tire/wheel overall weight should be a huge concern.  I want to run RE71Rs again. In Street Touring I can run up to 11" wide wheels and 315 tires.

Option 1: Forgestar CF5 19x11 wheels with 305/30R19 tires.  Total weight per corner is 58lbs.
Option 2: Forgestar CF5 18x10 wheels with 285/30R18 tires.  Total weight per corner is 48lbs.

The 285 tire is 1.4" shorter than the 305 and 0.8" narrower in tread width.  I have camber plates and a decent suspension set up.  Vorshlag helped me decide on which suspension components to go with.  They have a crazy amount of knowledge on making these cars go around corners. From my research I have found rotational inertia in the form of wheels and tires is not a huge concern in autocross. Is it? And that wider is better when it comes to heavier cars but some initial turn in response might be compromised. The shorter tire would make me lose a few mphs in second gear but would help my torque down low.  I'm not terribly concerned about that because I rarely touch the 2nd gear rev limiter.  What do you guys think? Is the .8" of tire width worth the 10lbs?
