TAG Motorsports recently received a first of KW Height Adjustable Springs for their in house VMW M4, code named "Black Betty".
Everyone who is over the age of twenty years old should know the song of the same name by Ram Jam, one of the better upbeat songs of the golden era of 'Rock & Roll. Now the trip down memory lane is done memory lane is done, we can get back to the matter at hand, the KW suspension system installation for this beautiful vehicle.
KW height adjustable springs kits are a great alternative to conventional springs. You don't have to be satisfied with a fixed lowering as you can adjust the height with the KW height adjuster even after the kit has been installed. This works well for some certain customers who like to frequently swap wheels on their cars. This allows the specifications for lowering in set numbers: front - 15-30cm/ 0.6-1.2inches and rear - 5-30cm/0.2-1.2inches.
With the individual height adjustments, the driving performance will be increased and the car should handle better in every situation. It also allows a great cornering speed performance improvement. All driver assistance systems and comfort features of an adaptive series suspension remain intact which is a big selling point. The KW Height Adjustable Spring Kit allows for individual height adjustable of the standard suspension kit, the adaptive damper control remains active, the vehicle specific spring rates, better steering behaviour and as mentioned the improved looks.
Our M4 is equipped with the adaptive suspension. in stock from there was a decent difference between all three settings but the "sport plus" mode was certainly firm. These new KW 'HAS' are allowing us to keep the active dampers, also its giving us the ride height adjustability that we are looking for. The ride in the normal "Sport" mode certainly firmed up from stock, but it really made the car feel much more stable, as it removed some of the bounciness the factory suspension had. However the firmness is not uncomfortable though, in the short drive from San Diego to Newport Beach over the weekend, there was a few dips in the highway that I know I have to prepare myself for (when I had the H&R Supersport Springs on), in the KW's still were more harsh, but it was a much sportier feel.
Overall, the ride is 'MUCH' better than going with just standard springs. the ONE negative side one would noticed with 20x10 HRE P104 wheels at the front, the new larger spring perch did not allow us to lower the car down to H&R Supersport Spring Levels. Also the clearance between a 20x10 front wheel, combined with the 265/30/20 Pirelli Tires at the front, allowed us only to go about 1.2" lower than stock.
For those that are interested in doing these springs and are recommend a 9.5" wide wheel up front with a lower offset. - TAG Motorsports, Initial Driving Impressions.
Its impressive by what we can see and the stance and overall look of the vehicle is simply stunning! A BMW M4 certainly benefits from lowering a set of custom wheels, same to what is installed on this build.
