I have a 19 C63S AMG. I found myself purchasing 17x10.5 wheels for my rear wheels. I intend to run 315s on the wheels and decrease the rotor to 300mm (as advised for my model). I wanted to ask a few questions regarding suspension and how I can make this fit.
1. I have kw v4s and a camber kit, what else do I need to do for my suspension to fit 315/35R17 on my 17x10.5 wheels?
thank you for all the help Slicks I want to run P315/35R17
You ideally want camber adjustment on the top and bottom of the rear suspension. Not sure if KWs have camber adjustability up top at the rear, but I know there are other aftermarket arms that have adjustability on the bottom. Also if you want to adjust rear toe, get the Carbahn Rear Toe Arms: https://carbahn.com/product/cbc63-31...a205-c63-c63s/
Not sure if you’re sedan or coupe? On my coupe 305/30/20 ntrrr2’s I rubbed in the rear on the inner back of fender closer to the mufflers when lowered. Got CarBahn’s adjustable coil over springs as well, so hopefully will be able to dial in a bit. Need some more stability in the rear at my power level.
Assuming you’re running some decent power if you’re looking at 17’s.
C63/S Sedan (and Wagon) we manufacture both upper and lower arm rear adjusters.
Upper adjustable control arms recommend in situations where “extra” Neg Camber needed for “tire to outer fender clearance” K-MAC are not soft extruded aluminum but hi-strength chromoly tube kit P/N 502226-1M $595 (Both Sides). Also includes “extra Toe adjustment” to compensate.
While Lower control arm inner adjustable bushes have the advantage of “retaining clearance” - top of tire to outer fender. Are easier to install (no need for control arm removal) and the advantage also of access to adjust - (single wrench). ULTIMATE - DIRECT ON ALIGNMENT RACK UNDER LOAD. Also uprating / replacing these 2 large soft rubber OEM bushings. P/N 502226K $480 (Both Sides). Also includes “extra Toe adjustment” to compensate.
C63/S Coupe. Coupe model these above “lower arm inner bushes” OEM / EX-FACTORY HAVE FACILITY FOR OFFSET SHIMS. BUT THEY ONLY ALLOW 3.5MM (LESS THEN 3/16”) CAMBER CHANGE !
WE SAW THE NEED FOR SERIOUS ADJUSTMENT AND TO BE ABLE TO DIAL IN PRECISE ADJUSTMENT - direct on alignment rack UNDER LOAD. K-MAC kit provides more then 4 times the adjustment range and like the Sedan / Wagon kit uprates the OEM soft rubber bushings.
At K-MAC we manufacture a TOTAL SYSTEM when it comes to resolving the lack of OEM adjustment (no front Camber or Caster and no rear Camber) - ALL TO DO WITH EVER INCREASING SPEED OF NEW CAR ASSEMBLY LINES and stopping to adjust settings is no longer an option - ONUS NOW PUT BACK ON OWNERS TO FUND PREMATURE TIRE REPLACEMENT !

FRONT SUSPENSION
Front Camber (ONLY) P/N 503316-1i $345 (Both Sides) fits all C63/S Sedans, Wagons, Coupes.
(Less cost then 1 Performance tire).
Front Camber (& Caster) - P/N 503316M $595 (Both Sides). Same as above - fits all models.
LIKE REAR ADJUSTERS BOTH ABOVE KITS ARE PRECISE SINGLE WRENCH ADJUSTABLE - direct on alignment rack UNDER LOAD. And also fit without special tools or time consuming need to remove control arms.
THE K-MAC CAMBER BUSHES ARE UPRATED WHILE THE CASTER BUSHES ARE MONO BALL / SELF ALIGNING also deleting the OEM soft rubber bushings - but still allowing arms to travel through their required suspension arcs !
With the result of significantly improving Brake and Steering response.
TRACK DAYS / COMPETITION - Front Camber adjustment allowing to finally be able to dial in (up to 2 extra degrees) of Negative Camber to reduce understeer. In the pursuit of hitting those corner apexes every time - and allowing to go deeper into the corners with increased Traction and Braking response. Rear suspension - allowing to also dial in for maximum traction. NOW THE CAPABILITY OF “FRONT AND REAR” ADJUSTMENT - ESSENTIAL. In the endeavour to make front row of the grid lap times !
Another popular kit - especially C63/S Sedans and Wagons P/N 502628K $480. Replacing / uprating the ‘6’ rear suspension multi link arm bushings. LESS REAR END TWIST, FLEX, LOSS OF TRACTION.
ESPECIALLY WHEN APPLYING POWER TO LANE CHANGE / OVERTAKE. While C63/S Coupe 8 out of these 12 bushes OEM / Ex factory “are uprated”. Remaining 4 K-MAC P/N 502628-1F $220
Owners that are into competition (not necessary on Coupe models) but Sedans and Wagons - Uprated strengthened Rear Toe arms to resolve flex. P/N 502326-3J $380 (Both Sides). Fit in conjunction with Rear Camber kit P/N 502226K.
