Was at KL Auto yesterday to inject some 'poison' onto myself and my K5.

Took up the Roar Buster + Bootlid + Comfort package and was amazed at immediate results, even before the foam is fully cured which takes approx 4 days.

A quieter cabin is realized even before I drove out from KL Auto; getting back on Jln Tun Razak & Mahameru stretch of road which I'm familiar, the road noise has reduced by quite a fair amount. With road noise usually escalates from 80km/h onwards, I was suprised that the noise level was as if I was driving at only about 60~75km/h when in fact, I was already hitting close to 140km/h!
One may say its just a psychological 'feel' but, going over rougher patches and some 'brick' roads, the usual jarring feedback from the suspension and steering feedback has reduced with my ultra low profile tires just gliding over these patches of road without much hassle & drama.

All in, it is $$$ well spent at KL Auto!
There may be competitors and debates on forum making all sorts of claims but looking at the results and the 'premium' clientele of KL Auto, Desmond's expertise and products speaks way louder than mere words in forums.

Shall give a more in-depth review in a week's time, once the undercarriage foam is fully cured.

Cheers!
