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”!
Our SSR Professor SP4’s in Titan Silver with a polished barrel.
That lip on the rear wheel is wide enough to lay a dollar bill lengthwise… but I forgot to take a picture of that. Also note the included valve stems. This is a rear wheel so we’re not worried about clearance on this wheel but the front wheel remains a concern.
From the side you can see where the inner and outer barrels of our 18×13 inch SSR Professor SP4 wheels are welded and sealed with silicone as added insurance against any air leaks.
