I did see some vw tires at 155sr15 on CL but they were too pricey.

Check https://twitter.com/FredCookeNZ/ for more pics of this thing today.

It was getting some tuning earlier on the mean streets of Florida :-D

The event this year had a sub-class of trucks, and this car took out that class with its wooden deck and won a prize! :-)

40 entrants overall with 6 DNFs, this car placed 11th this year! Not bad :-D

Lots of media online if you look around for GRM challenge 2017.

Current state of "tetanus". The front shot is altered - the radiator is moved back and the front "axle' moved forward.

We were in 7th place overall at the end of the two motorsport events (autocross and drag), but "dinged" hard in the concours. Lots of progress since last year, but the front two thirds of the car lacks serious attention and that hurt us in the car show. Regardless- the car is an absolute blast to drive. Looking forward to next year. Thanks to Fred for his help. Having a third brain and set of hands for the week was nice.

2018
The drags were canceled for 2018 due to repaving, so we focused on the presentation for this event. We cleaned up the interior, gave it some paint and built a center console.
Image

Also built a dash.
Image

Picked up some super cheap eBay gauges and added custom faces.
Image
Image

Designed and built a configurable tailgate that works as a normal gate flat/up, spoiler or is removable.
Image
Image

Created a Tetanus logo. Carved a block cut of the logo that was then stamped as a pattern on the diy denim scrap door cards. Added a shifter boot made from camo scraps.
Image
Image


We created a ficticious sponsor "Aunt Patty’s Opossum Parts" for our concours presentation. Played that out on tshirts, decals, temporary tattoos and a custom gauge housing for the tacho.
Image
Image
Image

Painted up some free honda steelies and “whitewalled” street tires from a Ford Ranger pickup for concours.
Image
Image
Image

Performance enhancements for 2018 included some semi-solid bolt-through motor mounts, no-name 15x8 wheels, a bed cover from renovation scrap and some old Hoosier take-offs.
Image
Image
Image

The current shirt art is the last thing I’ve created. It will serve as our team shirt for 2019.
Image

We’re under $1300 spent at this point. Boost is next for 2019. I have a crate of stock exhaust manifolds to use for the the build. We have an eBay “evo” turbo sitting on the shelf and a proper set of drag slicks and wheels. Tetanus is already running and tuned on Rx7 turbo II injectors so we'll just be expanding the tune for the added pressure.

Thank you very much for posting all of that, Rob! So awesome :-)

Will see what I can do for September, fingers crossed. (multiple meanings lie therein...)
