19×11 CLK63 Black Series Rear Wheel Build

The reason this build came up was due to the desire to run the Toyo R888’s in 265/30/19 up front and 295/30/19 rear as opposed to the factory Pirelli’s on the CLK63 Black Series. Those who track their Black Series have sought after this setup.

A 9.5 wheel is needed to run the 265/30 properly. Trying to mount this size on the factory front wheel looks terrible and does not perform as desired. The Toyo’s just run too wide and even a 10″ wheel would work. The idea behind the package is to not have to buy a whole new set of wheels just to be able to change to a different brand tire. This might not appeal to everyone but we thought some might like this option. Conversely now that we have the design in place we can offer a full set of OEM style wheels in any custom fitment desired or we can simply produce two new rear 19×11 wheels and move the OEM rears to the front.

We had our test car in for some additional fitment and testing and here are some results.

Again, we are producing a pair for a customer in house. Turn around time is about 4 weeks once ordered. Pricing will be $1200 per wheel for 19×11. Test fitment has been completed and the final offsets worked out. The first minor snag we have come across was that the inner barrels on the rear wheels are shaped different than the barrels on the front wheel. There is a step that is not present on the front barrel. The bottom of the outer tie rod end barely makes contact with this step when mounting the OEM 19×9.5 on the front. This requires you to run a tie rod end with a lower profile than OEM. So far all we have been able to source is one that would require minor reshaping to the bottom of the tie rod end to gain the needed clearance off the barrel. So this setup would require that the front outer tie rod ends be replaced or the customer can modify their own tie rod ends which is what we have done on our test vehicle. Knowing that some people may not have the capability to do this is why we are still trying to source an aftermarket tie rod to include with the kit. So far all we have come up with is one that requires minor re-shaping to clear. Also, in order to get the rear OEM wheels to look flush/proper with the new 11” we are running a 12mm hub centric spacer up front. I know a lot of the guys that run factory wheels also run spacers to increase track width so this should be a non-issue for most.

While working through this project we determined that you may not have the tie-rod end issue. Our understanding is that MB used different wheel manufacturers that produced some rear wheels with the step barrel while some did not. You can check by inspecting the inner barrels of the wheels on your Black Series to confirm.

As always, we are here to help and can walk you through these steps prior to putting an order together. email or call with any questions, thoughts or comments. The photos attached show the wheels through design to final product to mounted on the Toyo R888’s.
