Our BMW M4 demonstrator was amongst the first in the UK and only two days after collecting the keys we decided to take it to the Nurburgring to put the latest M Sport powerhouse through its paces. We were astonished by its performance and since its return have started the development work for our intended range of performance upgrades which, as with our GTR work, will touch on all aspects of the car.
As one of Akrapovics’ leading dealers we were delighted to receive the UK’s very first Evolution exhaust system for our BMW M4 demonstrator. The quality of Akrapovic exhausts is always exceptional but the M4 system in particular is exquisite; it is even available with its own dry carbon valance to compliment the quad carbon tail trims.
In the presence of Charlie from Akrapovic UK we were excited to hear what the new system sounded like and it didn’t disappoint! The car now has a much deeper more menacing tone and on full throttle sounds superb.
At the same time as fitting the new exhaust we also took the opportunity to install our prototype lowering springs before heading over to Silverstone GP circuit for a thorough testing.
If you are going to test new products there is nothing better than having a World Champion Touring car driver on hand to provide feedback. Our friend and fellow Akrapovic customer Rob Huff jumped at the chance to drive our M4 on track and the information our technicians could gleam from this was invaluable.
The new springs performed as we hoped and worked as well on track as they had on our road tests. The additional feedback from Rob means that some subtle changes to the ride height and spring rates should improve them even further.
