Mad Manthey Kit announced for 911 GT3 Touring

Missed out on a 911 S/T allocation? Manthey may have a solution


Manthey Racing’s at it again. Having worked its magic on the regular 992-gen Porsche 911 GT3 a few years ago, slashing four seconds off the base car’s blistering six-minute 59-second Nurburgring lap time, it’s finally gotten around to giving (what’s supposed to be) the more understated Touring variant the same treatment. 

The GT3 Touring remains a wingless wonder with the outfit's upgrades bolted on, but the new Manthey Kit does claw back some downforce with a deeper front splitter, extra floor-mounted turning vanes around the front wheels and a reworked rear diffuser with carbon fibre strakes. And, like the regular Manthey GT3, there’s a carbon fibre ‘aero disc’ that can be bolted onto the (also optional) lightweight Weissah-style 20-inch wheels, with all four rims combined saving 7.3kg. No word on just how much extra downforce the upgrades bring, but Manthey Kit-equipped GT3 Tourings should feel even more planted at higher speed.

Along with the aero improvements, there's a raft of chassis upgrades. Chief among them is the company’s coilover package, comprising four-way adjustable, aluminium-bodied dampers with new front and rear top mounts, plus there’s an optional brake kit with heavy-duty pads and braided lines for track use. On top of that, the outfit will replace the standard door sills with its own Manthey-branded (and very cool) illuminated trim, while a decal set with subtle logos at the base of the doors can be slapped on for an additional fee.

A 911 S/T on a budget, then? Well, not quite. The GT3’s 4.0-litre flat-six is untouched, meaning 510hp at a sky-high 8,400rpm and 347lb ft at 6,100rpm, but that's still only 15hp shy (and 4lb ft more) than the RS-based S/T. Manthey hasn’t revealed how much this all costs either, but expect to budget an extra 50 per cent on top of the price of the car. Alternatively, the suspension and brake kits, as well as the lightweight wheels, can be bought individually if you’re not keen on going the whole hog. You could also just bag a branded tow hook and tell your track day mates that you’ve had all the Manthey work done. Just make sure they don’t poke around underneath or peer into the wheel wells…

Or just buy the “Std” GT3 for the extra downforce. Suspension upgrades would be good. I am a bit disappointed they haven’t offered the lighter flywheel of the ST for a freer reving engine, std one isn’t bad though.

This looks way better that the standard GT3 - I'd prefer the extra downforce the kit brings without having the reduced visibility that comes with the rear wing.

Headline said Mad, I expected something utterly bonkers, but this is tame, and actually looks pretty decent. Nice motor too.

Lovely thing but I'm sure I'd be just as happy in a "standard" 911. Looks lovely though smokin

no downforce figures, but stickers, door trims and carbon diffuser strakes.
Sounds a bit 'visual' to me.....

Suspension and lighter wheels notwithstanding, I wonder what percentage of GT3 Touring owners will feel the benefit of this on track, when the standard GT3 is meant to be the track one, and this is meant to be the.... Touring one...

Has Manthey completed the online Porsche training module for maxing profit whilst minimising investment?

beautiful car as always though....

Not quite sure a body kit, shocks and wheels are worth that, but it looks very nice.

Interesting, none of the owners of 991 911R or 992 GT3 Tourings I know have complained about lift even at significant speeds, have you experienced downforce lacking in these areas?

Seems like Porsche charging money again for something that isn't needed, not that it'll stop the fandom coughing up their cash to have 'the best, because Porsche say it's so'.

what can I say, still looks lovely.
I guess its also a little bit lighter with the alu shocks and Weissach lightweight wheels.

I wonder how much in total though, guess its not much, but its at at important points.

There has been a number of arguments when the model was first released on the benefits of the wing (CFD and wind tunnel). It's not just a case of 'coz they said so'... There is positive engineering involved.

Based on all the ads on this site for modified 911s and restomod 911s, and their associated prices, I think it is a prerequisite that you have undertaken that training module before working on any 911, present or past!

Not sure any GT3, or Manthey, are majoring on they value-for-money argument.

Acknowledging that PH was first a TVR shrine, it does seem apparent that, not least because the TVR story is at best on an extended hiatus, that, even if only for the writers, that it has moved to the 911 as the celebrant wielding the sacred flame, if only because of the number of articles attending to this car. It IS special. So it would be good to do an article that tabulates cost, weight, power, downforce, acceleration and other attributes across the field of new, and used specimens.

Thats pretty much a GT3 Touring you describe.
