In Part 1 of our Wheel, Brake and Tire miniseries, we ordered a set of SSR Professor SP4 wheels for our RX-7 from Tanabe and were patiently enduring the two month wait for them to be built in Japan. During that time we fitted our car with a Stoptech Trophy big brake kit (in Part 2) hoping they would clear the wheels. Right on schedule our wheels arrived and we were able to pick them up from Tanabe's facility in Torrance! In Part 3 we’ll finally see how close all our guesses were to being “good enough”!

“Who is GT Radial?”
That was the 1st words out of everyone's mouth when reading the SCCA Solo Contingency Program page.
What seemed to be a more known name on the West Coast was virtually unknown throughout the rest of the country. The next big question is “What tire do they have that we will want to use?”
I am sure that there is no other form of auto sport that combines the aromas of oil, gasoline, and rubber quite so well as drag racing. Then there is the sound! There is an adrenaline rush as the whine of superchargers, the whistle of turbochargers, and the ear drum crushing thump of massive V8 engines roar off the line. And you had better be ready at that line or your time will not be near 12 seconds (it was a test and tune night. I could have used Dom's 10 second line, but not that many cars were running 10's!) and your timesheet will reflect your poor reflexes. There would undoubtedly be a few comments when you returned to the paddock.
Remember that blue E92 M3 build that we were featuring here on MotoIQ a while back? The one that seemed to fall off the face of the Earth? Good news, it’s still out there and many of you may have already seen recent photos of that project bouncing around the internet without even realizing it’s the same car. Unfortunately the car has progressed so drastically and quickly that I just couldn’t keep up with the articles. Now that the car is largely “done” I have some time to get our faithful MIQ readers caught up.
Our Project Z was a pretty good example of what a naturally aspirated VQ35DE could do. However, our VQ had become old and tired. It was worn out from a lot of minimal maintenance street miles, track days, drift and professional stunt driving practice and had started to develop some rod knock. Luckily we were able to stop before serious damage to the engine internals resulted. However an engine rebuild was in order.
Our objective in building this engine is not to build the most awesome NA VQ possible or even to get tons more power, but rather to perform an economic build to address some of the VQ's durability shortcomings, replacing stock parts when necessary with some good quality aftermarket bits.
Ever since our projects, Project FR-S and Project STI got the Stoptech Trophy kit on them and we felt how amazing and confidence inspiring those brakes were, we HAD to have them on the FD. After all, it IS our flagship project and that nickel finish is just way too bad ass and EXPENSIVE looking! Stoptech makes a Trophy Big Brake kit for the FD RX-7 and those are the brakes we alluded to in the last article that our wheels needed to clear!
Rob demonstrates the functions and importance of an oil pan baffle from Moroso, which can save your engine at the track. Then, he shows you how to install one.
Wall Speedway isn't called "The Gauntlet" for nothing. The guardrail here is an industrial strength can opener that shreds any fender, bumper, or tire that dares to get too close. Throw in some East Coast thunderstorms and you've got exhilirating battles. Fredric Aasbo took home his first top finish here last year. Could he make the Wall his bitch again?
Two installments ago we put the Rocket Bunny wide body kit on our Project V8 RX-7 and if you remember it was looking pretty damn stupid on the stock wheels and tires inboard at least 6 inches on each side. In Part 1 of this 3-part update we'll be feeding you over the next 3 weeks we get some ridiculously large tires for our FD and try to find some wheels to match!
The Evasive FR-S with its wild aero and wide body had been shipped to Japan for a time attack battle at Tskuba Circuit leaving the team without a car to compete in. Instead, for this years Pikes Peak Effort, Evasive teamed up the Mackin Industries to run their FR-S up the mountain in the Time Attack 1 class. We had previously worked with Evasive and Mackin on setting up this car at Super Lap Battle so it was reasonably dialed in. However, it needed another round of upgrades to tackle Pikes Peak. The work was done on a super low budget in quick order. Turn 14 Distribution was an essential part of the effort donating many parts and helping with the budget.
Lets take a look at what was done to the car prior to the event!
The McPherson strut suspension found in our Mustang has some good and bad points. The good points are that it is simple, lightweight, inexpensive to produce and takes up minimal space in the car. This in turn allows room for more narrow shock towers so the wider DOHC Coyote engine can fit. The bad points are few but perhaps the worse is that strut type suspension has some compromises when it comes to geometry, particularly when lowered.
The benefits of lowering a car can be nullified in a strut car if the car is lowered by more than just a little. Often lowering a strut equipped car makes the car handle worse, particularity in the front of a strut equipped car where over lowering manifests itself as increased understeer. Some lucky owners of cars where there is a healthy aftermarket have off the shelf solutions to fix the front suspension geometry. If you are a Mustang owner you are in luck as Ford Racing has a well engineered geometry correction solution available for you right at your local dealership's parts counter.

The grand majority of MotoIQ readers have been to some sort of motorsports event. Whether participating in a track day or simply spectating at a pro event, we're always looking for ways to get our motorsports fix in. Until now we have always had to make a choice between being part of the action or just watching. Not anymore! The Street Driven Tour is a motorsports bash with something for every gear head. You want to watch some road racing, they've got it. You want to go on a drift ride along, they've got that. Want to play some drift-soccer, they've got that too!

You likely have your perceptions about Canada - the country north of the United States that is full of mountains, forests, and calm, happy people. So I am sure that the title Radical Canada may make you wonder. Perhaps you have read some of my other articles and realize that, on the race track, there are some pretty radical Canadians. Here, however, my focus is upon the Radical sport racer.
When we last left our Project SC300, aka “Damnit”, we had just sat the new Fuel Safe/Radium Engineering fuel cell into the trunk area in order to mark out where we would cut. We had also removed the rest of the factory stock hard fuel lines to make way for our fancy new braided stainless lines that we will assemble ourselves. Now follow along as we mount the cell in place.
