Problem with all the GT3 Mclaren cars (including 720 GT3X) is that you need mechanics at the track and in between sessions to support the car - and that the running costs by far execeed those of a Senna or Senna GTR … I have had a long talk about this with the race mechanic of my dealer who supports the customer teams and my dealers own race team for 24h races … he showed me the prices and changing intervals of the GT3 and they are 4-5x more expensive to run than a Senna GTR which basically will only need new pads from time to time, tires and very seldom new disks …

does not mean that a Senna GTR is a cheap car to have, but compared to a real GT3 it’s quiet cheap to maintain (of course much more to buy)
not sure if i agree with the running costs of a Senna GTR, you need mechanics for that, and parts etc are pretty much the same.
when we race with the GT3 car we change parts well before the break (hopefully) according to a lifing schedule. You cant have a 500 dollar part fail and ruin a 100k weekend of racing etc.
BUT for our track cars we change parts more or less when they fail or about to. not the end of the world if something breaks on a track day. so I think i can with 100% certainty say a GT3 is not 4-5x more expensive to run as a track day car than a Senna GTR. and that is just the cost of driving the car, never mind purhcase cost, financing cost on that 5% on 1.5mn pays for a few tyres etc....
the ONE cost that will be significantly higher with a race cars is your tyre budget. you wouldnt do more than 250km per set and that is stretchingit.
But you can drive comfortably to the track in whatever car you want, if something happens on the track, you just drive back home in that comfortable car

as to tracking road cars, the brake pads on a P1 was GBP11k and the disks/rotors GBP50k so not exactly cheap.
The Senna road car isnt exactly cheap to run, considering how fragile it is.

IF i had to have a road car as a track day car there really is only two alternatives, a GT3RS or a GT2RS. at least you know they can sort of handle a day a the track and you will most likely still be able to drive back home ;)

..... don't forget the AMG GT Black Series :)

The GT3 version DID just win the 2023 'GTD Pro' Rolex 24 @ Daytona.

this question comes up a lot on this board, hardly surprisingly...

the one thing that hasn't been mentioned and isn't mentioned enough is that the driving experience of a proper race car or track car on a track is night and day compared to any road car... senna, gt3 rs are pale comparisions of their track dedicated brothers or sisters... once you have learnt to drive a race car to some percentage of its potential any road car feels soft, slow and lethargic.. that doens't mean that a road car can't still be fun, it can, but compared to the precision of a race car and indeed the 'built for purpose, won't break in an instant' construction, if you really want to enjoy being on track there is ultimately only one option.. not to mention the safety aspects of the race cars ... again if you're going to have a crash you really want all the safety aspects of a race car, plus you want to be in a car which has seats taht were designed to accept a hans and all the belts designed and installed for purpose, not cosmetic add ons..

of course tracking a road car is a first step to going down that route..and there are many many very satisfactory steps leading to owning or experiencing a race car and that is a journey that any enthusiast should and will enjoy no matter what their level of skill...

as for running costs, i personally believe over the long term a road car is more expensive.. i think the discussion here has been about 'teams' to run a race car or track car and of course when you first buy one of these thngs as a noob, someone somewhere is going to charge you a fortune.. but it doesn't and shouldn't cost the earth..

you may well pay a little bit more for a slick tyre day than you would a road tyre day, but that's normally cos numbers are more limited..

but you use the same amount of fuel, as alex says you mgiht use a bit more in tyres, but ultimately the wear and tear on a car that you're using for track (and not racing which is different again, with lifing and the like, as alex says) is less than it is on a road car, and of course its built with bits that are designed for purpose not with some puff marketing in mind.. (here's looking at you CCB.. )

in extremis, i can run my 458 GT3 or 650s GT3 at silverstone for next to nothing... its a slight anomaly as on a BRDC we don't pay for the track, we own it so why would we.. and i have one mechanic and one engineer .. that's all i need.. (and indeed that's what the team proposes to me)..

then you might find some like minded fellows.. and it gets even cheaper..

its true you need a truck or at least a trailer to move it... but transport ultimately is pretty cheap..

and the experience is many multiples of what you experience in a road car..

so in real terms, you probably pay 1000 of your local currency for track entry, 1000 for support (probably less) plus whatever you want to spend in fuel and tyres...

plus maybe a few hundred to get it there... if you need that bit..

steel discs on GT3 are 500 a pair..

Drivers were Cameron Lawerence 2:00.08 & Rafael Martinez came in at 2:03 I believe. I am sure Rafael will post some in car videos soon on youtube in the future.

Getting into the 2 teen's is fast. Getting around 2 Minutes flat is really fast! I was told that the car will do under 2 minutes in the future as the set up was not quite where it needed to be.

Thanks for the video and update, 2 min flat is crazy fast, what a great car and driver!

Some HUGE misconceptions about GT3 cars here:

You do NOT need a full raceteam support to run a GT3 car at all, so long as you find a good specialist to do your engine/gearbox intervals you will be fine. Most of the teams I know and work on mine and my families cars tend to just bring the car for the race weekend, throw it down and get running with barely any extra thought than compared to a road car.
Main exceptions to this are usually when power limits are imposed for the weekend based on BOP changes, it is better when these are physical as its a quick 5min job to change, otherwise its a laptop with changes for the Bosch ECU

Yes you will need equipment to support you, elephants feet, air system etc etc but that is just part of having any dedicated track car, just a bit more expensive.

The Senna is a superb road car, but even 2014GT3 cars are be much faster round a track.

The 720sGT3 in BGT/IGT/GTCEU BOP is limited HUGELY in terms of setup. 4deg max camber front and rear, fuel tanks limits. Even putting the car on the grid needs its ballast box nearly entirely filled

The 720sGT3X ignores BOP and will be much faster that the GT3.

My guess is 20seconds faster than a senna around Silverstone GP at least.

A Championship winning GT team look after most of our cars, and it is cheaper than dealer prices thats for sure!

Saw a Pro driver showing what an owners Senna can do round the GP circuit at Silverstone and posted a sub 2.07, in good conditions last year.

Would be interesting to see what a 720GT3X could do.
Certainly would shut up all the Porsche GT2RS Manthey fanboys.

We know a little more now:


A 720 GT3X was 3s faster than an LMP3 prototype at Super Lap Battle this year (at COTA) and this crazy thing:
