Many of you will have heard of Manthey-Racing, the most successful and respected of all private Porsche race teams today, so much so that it is no longer private at all, but majority owned by none other than Porsche itself.

It has for a while also produced a suite of upgrades for Porsche’s most exciting road cars, sufficient for its GT2 RS to lap the Nürburgring in 6min 40sec, seven seconds quicker than the standard car and by a distance still the quickest time recorded by a road-legal car. The only problem has been that the upgrades have not been officially available in the UK. Until now. Manthey has just appointed Porsche specialist RPM Technik as its UK agent, so I tried its GT3 RS MR to see if it was worth it.

If you want the whole kit – the nose-to-tail aero mods, the magnesium rims, Manthey coil-over suspension and brake modifications, it will set you back £69,000. And the first thing I’d say is that if you’re not going to be driving flat-out on track, don’t bother, it’s not worth it. If you are, oh my goodness…

Of course there’s more grip, particularly at aero-sensitive speeds, but the real reason it’s so much quicker is because it’s easier to drive on the limit. That slight edginess of the standard GT3 RS has vanished. You just drive around, relaxed, wondering why everyone else is going so slowly. Utterly addictive.
