The BMW Z8 is a rare car. It may be so because the ultimate Bavarian roadster was crap or it may be so because “we don’t get it” but it is rare.

Reportedly only some 5703 units of the BMW Z8 were built and sold over the four year period it was on sale. That’s just the tip of the problem.

Of these units, some have certainly been crashed so far (handling may have something to do) and others have already been tuned up by other companies.

With all of this information available and with tuning being a principle of exclusivity, why on earth did somebody at Senner Tuning say, you know what… we should make a kit for the Z8.

It makes absolutely no sense but it doesn’t really matter because it’s happening. Not that I don’t think they won’t make any money on it but Senner Tuning have thankfully kept things simple.

The BMW Z8 gets a new sports air filter, a new exhaust that’s less restrictive and the proverbial ECU remapping. That translates into an output of 450 horsepower and 394 pound-feet of torque from the 5.0 liter V8 engine.

With these new figures the BMW Z8 can get up to a top speed of 186 mph.

Oh and just in case you weren’t known as being insecure that you needed a very rare car tuned up, Senner Tuning will fit new 19 inch Work Schwert SC1 wheels and a coilover suspension and Racing Gold varnished brake calipers.

If you’re interested, the Senner Tuning kit for the BMW Z8 costs some $25.000. Not cheap, but you shouldn’t expect that attribute to really come anywhere near the Z8.
