Upgrading our kits is the easiest to do out of all the options available. Your question depends on what you mean by top 3 kits
VF540 :is the most popular kit being purchased this year(universally upgradeable components/less labor and downtime)
VF620 :most # of units in operation worldwide
VF650 :highest performance but not everyone has a full sports exhaust and easy access to 93 octane.
Going from a VF540 non-cooled to a VF595, VF620, or VF650 cooled is the highest cost but you also get the most:
- Slide-in air:water heat exchanger in existing universal manifold
- Front mount radiator assembly w/bracket
- Factory grade water lines and fittings
- Bosch water pump
- upgraded pulley and belt
- Custom VF-software flash
(A new Hex Flash OBD2 Cable and PC program will be included for 2nd hand customers)
- 1 year/12 mile warranty for the upgrade parts
Once you have the ^above components, the small difference in price to upgrade is well worth the value in the tune, belt and pulley and makes Upgrading Easy. This is the same for other S/C options, unless other manufacturers require other extra necessary parts. Once you get behind the wheel of a 620/650hp boosted M3, it's hard to want for more. The tamer VF595 is suited for those looking for more power and air-to-water cooling without the higher $$ and boost psi of the 620 or 650. The +175hp jump with a VF595 is usually enough to satisfy the hunger!
