All of the racing I've done in 2017 already wore out a set of the new Falken RT615K+ tires. With all of the experience I've had on the old Falkens and now using up a set of the new Falkens I decided to write a review.
The full review is here:
Falken RT615K+ Review
The short answer is that the new Falken tire is measurable better than the old.
Finally, some folks may have noticed a splitter in some of my pictures. I built a simple splitter last year and have been running it for a while now. I kept getting questions about it and why I chose to build it out of plywood. So I wrote how to article here:
how to build a DIY plywood splitter
As I talk about in the article the four main materials I've seen people make splitters out of are: 1/8" aluminum plate, alumalite, carbon fiber and plywood. After a bunch of research I decided to go with plywood. As it is way stronger than alumalite, way lighter than 1/8" aluminum and way cheaper than carbon fiber it seemed like the best option.
