When I checked the tracking data this morning I noticed that the Grand Hero had moved to the other side of the harbor and that there is a road into where the ship is now berthed. Hopefully, that means that it will be off loaded there! I have no idea how long that will take and how long it will take to load it onto a carrier(s) for the trip to Cincinnati. I can only hope it will arrive there sometime this month!

It would appear there are BMW engineers with too much spare time on their hands! They could put their skills to better use designing a better GP3 production and delivery process!

In Hamburg (more bridges than Venice ) VW engineers are a step ahead. OK old design but sturdy !

Does anyone have any info on which Stainless Steel brake lines we can use to replace the stock ones? I'm about ready to start prepping for track days

Missed this one. The list is quite extensive and has been discussed through this thread but scattered through out. So a snapshot as I can remember it... The rear wing and front aero. Special steering knuckle for a wider track and more camber. Not sure what else they have done for camber. Underside braces, springs and shocks, Engine management and “traction control” unique to the GP. Larger front brake rotors (not sure if the caliper is different or not). Not sure about rear brakes. Wider wheels; better tires. Lighter weight (by about 200#, if the post being quoted are correct). Limited options; one version has no AC. Have not heard if it has special brake pads (I would guess yes) or if it has different sway bars. Engine is beefed up with stronger piston and what not. I am sure I am missing something...

That I don’t know. The MINI USA web still shows a 6 speed manual and an 8 speed automatic option, but who knows if that is up to date (still showing as 2020).. Or if the 8 speed is the same as the GP’s. The Hatch JCW and Clubman JCW automatic are both called a “8 speed sports...”, for what that is worth. And the Clubman’s auto is the same as is in the GP. I’m back to - don’t know...

Although, I believe the programming for the auto is different.

Looking through the parts, the F56 JCW and the F54 JCW both have versions of GA8G45AW with different part numbers and the F54's is specified that's it's for an AWD vehicle. The latest part number for the awd version is 24009844237, is labelled GA8G45XAW - ENW and shows as for the F39 M35i and the F60 JCW, could just be the F54's parts haven't updated in bimmercat yet. The F56 JCW uses part 24009844227 and it's labelled GA8G45AW - E07. No parts info out there for the GP3 yet to see how they compare.

As said one year before for 2021 Master Plan U30 a GP3 manual will be considered. the 50 kg less on the front are appreciated and compensate the cage.

The MINI 6 speed? Or some other, like the Challenge car sequential?

So, maybe the AT guts are the same, but the AWD Version has the addition of a transfer case or the like? And it is conceivable that the GP and JCW use the same box? Or am I over thinking this...

To me, I am far more impressed with it than a JCW, obviously lock to lock is not 1/4th, but it is surprising how fast it responds, the weight is lighter than sport mode but the return to center is QUICK!

Internally mechanically, the 8 speed in all cars is the same. The Transfer case for AWD cars is different and programming is different.

the biggest difference is BMW’s ARB traction control program being implemented in the GP, this allows the transmission to shift far more aggressively while holding traction.

I think there is a typo in your post... Maybe that was supposed to be
sport mode
?

but:

that would sound like they added caster to the front suspension that the JCW doesn’t have.

The unique traction control is BMW’s ARB system. The front brakes and calipers on the GP are the same design as the F54 and F60 JCW and are fundamentally different to the F56 JCW calipers (I own both). However, the GP uses “steel” brakes, which likely refer to the pistons inside the calipers, as previous JCW calipers have used plastic pistons. Rear brakes are same size and design as F56 JCW and therefore S, however, they work much better thank to the functioning rear wing (I’ve actually already got bug guts where the wing presses the air down on the top of the car, it works). There are only 2 options, and US cars had no option, you either got the track variant (with racing tires, without an) or the touring variant (summer tires,with ac). Brake pads and sway bars are better than stock JCW but no different between track and touring variant.

you missed the solid motor mount. It also has the GP traction control mode. The fenders and geometry mean you can fit 235 width tires without messing with the fenders. The steering response is different than other cars because it has no sport mode. Also this is a small thing, but the 3D printed paddle shifters are larger than the plastic ones on the F56 JCW. However, it makes a huge difference. I’m missing a few other things as well

But my F56 JCW with all the bells and whistles is a fantastically fun beast and fast and with a few tweaks produced 279 HP and has been a comfortable, flawless, twisty mobile, not perfect, but it suits me and with 60K miles it is still going strong. A great DD, but a fun beast in the twisties and adequate on the track. I know I will miss the dynamic damper that it has when I am traveling to and from the events, but the GP3 has all the power I can handle in what is a still small car and it will suit Paula and I for as long as we continue to drive twisty roads and there are a lot of good ones that we haven't driven yet singing the siren's song for us. I hope to have it later this month and have it wrapped and a few other modifications that will make it mine and then the agonizingly slow break in period, but we will enjoy that process as well. I am researching tires now and most likely will go with Michelin as I have had excellent results with their tires on all of our fast toys over the years. We will break it in with the Hankooks or what ever OEM tires that are on it, then make a decision of what we will use on it. We have the Michelin Pilot Sport AS3+s on our JCW and they are a good performing all season all weather tire, but not up to hard tracking duty, but a nice compromise and they are not runflats which we don't like due to the severe ride quality. We also have them on the Z06, but they are the runflat version and for our use the are fine, but not a particularly good track tire, but adequate for all around driving use. Most likely I will replace the OEM Hankooks with the Michelin Super Sport category tires non runflat and carry my compressor kit, slime, etc. It has served me well for 4 years of hard twisty driving in the JCW. I will keep up with the forum posts to see what others have done and what works best for them based upon their driving styles and preferences. It is fun speculating what will and won't work and the various solutions that others find that suits their need. We are going to have fun with this little beast whatever we decide to do. Bring on the Hondas, M2s, the Alfa Romeos, and other challengers and we will all have a good time and share our stories after hard fun runs and track days and talk about what a great day over dinner and drinks. Then do it again the next day and have too much fun. I miss the mountains and need some good runs to relieve my covid 19 blues!
hey, just a heads up, the Hankook summer tires on the car are not run-flats and the GP comes with the compressor kit. I was originally of your mind that I cannot wait to get them off the car for some Michelins. After driving on them, I have to say I’m more impressed than I thought I would be.

235/40/18 way better than the stock 225/35/18, the car comes up 1,5cm and the wheelhouse looks fine front it needs 3mm spacers to have 5 mm clearance.

Did your dealer complain about them not being the correct size or did you go to tire shop and they had no issues with it?
