SL55/63/65/R230 AMG: Veloce Performance Announces Suspension Lowering!!
Everyone wants someone else to prove something that for all intents and purposes is academic. Since we all have these cars, I can derestrict them....and let you guys go prove it for yourself........AND have some fun in the process!!

Ohh just like your HP claims for you ECU tune!
LOL!

Anyway I hope we can get back to the subject of this thread i.e suspension lowering.
Just using the car's setup and not taking into account if it even has enough HP to do the job it doesnt work...
Final Drive Ratio: 2.82:1
RPM limit: 6,500RPM
Rolling diameter in inches
--------------------------
275/40ZR-18 rear tires = 275 * 0.40 = 109.6 * 2 (top and bottom sidewall) = 219.2mm
219.2mm/24.5mm per inch = 8.947in + 18in tire = 26.946in rolling diameter
max mph = (rpm x tire diameter)/ gear ratio x 336
max mph = (6500 x 26.946) / (2.82 x 336)
max mph = 175149/947.52
max mph = 184.85
I'd love to see an SL55 go over 185mph in stock configuration.
Did I miss something in the math?
1. We use 285/35-18 rears; some up to 295/35-18
2. Final drive on our cars is 2.62 or 2.65, I don't remember off the top of my head. Either way, it is not 2.82, which is used on the standard SL500 only.
3. If I am not mistaken, the final drive is for the 1:1 gear, and we have an overdrive 5th.

E55 has 2.65
AMG had to slow the E down with the lower Rear End.
Had both and the shift points are different and I read the numbers off the diff housings as well.
