Mercedes-Benz McLaren SLR is powered by a hand-built 5.4 liter supercharged V8 – 626HP (460 kW) at 6,500RPM and 780Nm (580 lb-ft) at 3,250RPM. Renntech boosted the engine to whopping 750HP (551 kW) and 992Nm (735 lb-ft). The result is thanks to upgraded headers, exhaust, intercooler, and an ECU re-map.

Additionally, the tuned SLR comes with big brake system behind a set of ADV05 Deep Concave wheels – 9.5 J x 20"at the front and 10.5J x 21"| at the rear fitted with proper tires. The rims have a matte black center and gloss black lips and inners to create the ultimate hyper car.

Nothing is mentioned about the prices of the performance mods as well as the set of wheels.
