SSR Professor SP4R Wheels



Why should I install SSR Professor SP4R wheels?

A professor always taught philosophy. And SSR's philosophy is spot on with the Professor line of wheels. Specifically, SP4R.  The Professor SP4R is a three-piece wheel that consists of an outer rim, an inner rim, and a center disk. The outer rim of the SP4R is welded to the inner rim. The center disk is then bolted, combining the three parts to make a bespoke looking wheel that is lightweight and stiff.

SSR's SP4R is a three-piece wheel consisting of an outer rim, an inner rim, and a nose. That piece is made of a slightly different aluminum alloy to ensure that the strength and lightness are evenly distributed within the wheel. This is what SSR is all about: wheels that look good and just about every aspect, but also equally important that this set of high-end race wheels should outperform the competition. 

Features:

  • Concave Disk
  • 3-Piece Design
  • Heat Treatment Manufacture Process
  • Included: Center Cap, Air Valve
  • Available in 16 and 17-inch diameters
  • Flat Titan Silver and Flat Black finish

The three-piece SP4R is made up of an outer rim, inner rim, and center disc, allowing SSR to offer a wide range of offsets and ensures proper fitment specific to your vehicle. The wheel's inner rim is heat treated for strength, using the HTM (Heat Treatment Manufacture) process, which allows for the use of a thinner material to save weight. With weight and high strength in mind, each section of the wheel is engineered using different grades and aluminum thickness according to its purpose. SSRs racing heritage and manufacturing innovations have allowed the creation of SP4R that is both super lightweight and high in strength.

Their 3-piece wheels will fit great, turn heads and continue to surprise you during your daily driving experience.

Heat Treatment Manufacture

After the forging or casting process, which depends on the model, once the wheel is thoroughly cooled, it undergoes a heat treatment which makes it even stronger and lighter than it already is. The wheel's inner barrel is then heated a second time as the interior of a wheel is generally where much of the tension happens in just about every driving situation. This heating makes the barrel as light as a feather and capable of withstanding tremendous amounts of energy, even in racing environments.

Why Should I Install Aftermarket Wheels?

  • Aftermarket wheels have been engineered to be lightweight, which is why these see the primary use in motorsports
  • A lighter wheel reduces un-sprung weight, resulting in faster acceleration and significantly improved handling
  • A bigger wheel allows space for much larger brake rotors and calipers—usually a must when a car is built to race
  • A larger wheel is more attractive in design compared to boring stock wheels

The SSR SP4R wheels are ready basically for anything. They 're made with highly tuned cars and racing in mind. SSR Wheels' SP4R is a top of the line wheel that will make your ride look amazing, behave more like a race car and give you faith in the part of your car that needs to be the longest lasting. The wheel is also incredibly lightweight to make you blast off the line much faster and smoother.

From JDM to a supercar, the low weight ratio of each wheel offered in the SP4R wheels will increase both your track time and pictures taken at car meets.
