The MR suspension kit is passive so you have to disable the PASM part of the ECU I would think?

If so, there's the warranty on anything electrical in your car out of the window?
the pasm unit is a seperate control box and can be quite easily overriden without affecting any of the rest of the electronic systems. Plus if there's a warranty claim on electronics etc or anything even vaguely related, it's pretty easy to just plug back the old unit.....

Or this is the case of PASM replacement e.g. DSC thumbup

Of course, nice one folks. I totally forgot about the DSC controller and how that works e.g. separate damper control box.

As you were! biggrin

I thought Manthey was owned (or significantly owned) by Porsche so the upgrade kit is probably factory approved.

It's not approved just because it's Manthey unfortunately. Only the kits for the 991.2 GT2RS and GT3RS are warranty approved from memory, and I'm not sure the 3RS kit is in the UK although it is in Europe? That was the case with the 3RS a while back but things may have changed.

I've not seen the GT4 kit, either 981 or 718, announced as a Porsche Tequipment offering.

For GT4, It’s not direct back to back in the UK… however Manthey cover their parts for 2 years… and Porsche will work with you on a case by case basis.

We are not talking about loads of parts… it’s quite a light touch kit…..



Not sure how 4 dampers, an aero guide, and fancy headrests can reasonably trash an entire warranty. Lol.

I've just bought a used 718GT4 Clubsport with PCCBs and wondering what's the best bangs for bucks mods for it. I'll be doing at least ten track days next year and want it tied down properly to give confidence to push harder on track.
We had a chat about this with you at Silverstone in August if you remember. Excluding new dampers I've looked at the kits from Suspension Secrets, String Theory Garage, JZM and RPM and still pretty confused.
I'm interested in the KW 3 ways Clubsport in JZM's website however can't work out why the 981GT4 ones are nearly £2k cheaper then the 718GT4's. Offset front mounts are essential IMV which are included with the KWs as well as the MR ones.
I might send you a PM before doing anything rather than trust anything the retailers tell me.

It's interesting this Tequipment mess....in Australia all kits right back to the Cayman GT4 MR and individual parts are available via the Porsche dealer network (Search Porsche Melbourne) and fitted and serviced by them. Shown as the Manthey option not tequipment option....In Germany its the 991.2 3RS and 2RS parts and kits (but just brake lines and coliovers) from what I could see, here it's something else....and in Germany you would go to Manthey anyways. I wonder if JZM and RPM have a distribution agreement that limits Porsche UK's ability to offer more fully?

I think it depends how far you want to go, how deep your pockets are and how fast a driver you are. I've gone along the lines of the old 981 GT4 MR chassis kit with Clubsport race car parts and kept the standard dampers which I always have in their Sport Chassis setting. I also have Manthey braided hoses and will be changing brake pads soon for something a bit more consistent when hot, but I do have a full set of PFC discs and pads on order too.

I don't see the MR kit as a bang for bucks option for an average driver like me but it's certainly a great one, especially if you're looking to join the Manthey track day scene.

Bang for buck, will come down to a small package of toe arms, Clubsport/RS/Offset top mounts, braided lines, uprated brake fluid and uprated pads.
With a decent alignment… GT4 is a comprehensive piece of kit.

However, the car is very softly sprung on the front end… and when coming from an RS product like Taffy is… it’s going to be noticeable… the main evidence is the weight transfer forward in big stops, that dip the front, lift the rear and result in a tail waggle as dynamic toe changes through damper extension. This can be mitigated a bit by added more static toe (via the adjustable toe arms)… but really, you fix by increasing spring rate on the front.

To that end the Suspension Secrets package has all the right parts, for a ‘basic +’ package IMO … and you can tweak it by also adding GT3RS LCA to get more camber and wider track width… where top mounts only will give you camber… but reduce track width.

The full MR package is a decent amount of money… and you don’t NEED to all of it. The dampers are definitely with the money,
The aero less so probably, as there isn’t much to it.
You can get a number of the aero elements from the 4RS now… but not all… and then you are effecting the aero balance of the car… if you can notice it.

The main point of full MR package is that it has all been developed and tested together.. gives you the maximum capability of the car, to grow into, and is THE recognised name for Porsche performance kits and not just a collection of part that someone has modded their car with… it’s a full stamped product set.

Depends what you want really. This stuff does not make the car itself faster, if you drive it the same way…. The purpose is to give the driver confidence in how the car will behave and that is what yields speed.

It certainly is, and this is the route I've gone down thus far thumbup

Yep, I've noticed this and I haven't found it too much of an issue as yet. If you're an advanced enough driver you can also use this as an advantage to induce some lift-off oversteer to help the car rotate around tight corners. Way above my pay grade though biggrin

I mitigated this by having the LCAs shimmed to a safe limit before adding the remaining amount of desired camber via the offset top mount.

I agree T, but if we're talking bang for the buck you can get a similar result much cheaper. RPM are listing the MR kit (without wheels) at £15,455 plus fitting. So far I'm in for around £2200 for the chassis mods and if you include brake pads and £6,844 plus fitting for Manthey coilovers (RPM's price) I'd be under £10k and £5k+ ahead of the MR kit for a very similar setup.

Like you say, it depends what you're looking for and how much you value the Manthey package as a complete set smile

GT3RS LCA would net you even more track and camber using the same safe number of shims…if you find you need more, or you could take shims out to achieve the same camber numbers as you currently have… all stuff to play with.

For your price…you won’t get the fancy headrests which are worth 0.75 per lap on a 2.3 mils circuit. hehe
Fortunately exchange rates were kind to me and I haven’t paid anywhere near that full price for my complete kit car… fully built and set up. Shop well!

The biggest bang for buck is not parts at all but seat time and tuition.. as I said… this stuff is just tools and doesn’t not make the car go faster automatically…

True, but I have plenty of camber and a few mm track width increase isn't something most people would get a huge benefit from I suspect.

Ha ha, so true! I hear exterior stripes have a similar effect..... wink

So true. I'll be researching what tuition to have next during the off-season...

Ok….strike ‘crash’ and replace with ‘malfunction’
Dude… it’s suspension. What exactly is going to malfunction? This isn’t some chav slamming the car with Gaz Golds, this is a 51% owned by Porsche racing team

And if you had an issue, guess who will sort you out…

A bargain. I think one went pre specced for more than that I heard.

And I thought all these gt4rs cars went to loyal honest customers who will never sell them unless they go back to the supplying opc!

We that’s two Uk rhd cars being offered around for sale already..
