Cupra r st tracking

[Damo H]

Yes 5F just denotes it's a Mk3 Leon, nothing to do with body type.
Both the Leon hatch and the ST have the same wheel base and the ST is only something like 20-40kg heavier from memory so I imagine there is no need to have different suspension geometry based purely on hatch vs ST.
The Golf Estate and Octavia Estate both use a longer wheel base platform vs their hatchback versions so I could see the possibility of requiring different geometry on these models.

Mk 3 Leon, hatch/estate, Golf hatch/estate and Audi A3 hatch/saloon all have the same wheelbase length (5 door versions anyway not sure about the 3 doors TBF). Explains why the arse on the Golf Estate is so, well, big.

Its only the Octavia hatch and estate that have the 50mm longer wheelbase in this gen of the MQB platform. Not sure if that changed for the newest gen.

Thanks all

I still await feedback from Seat Uk via the dealership.

The correct settings are the most important thing to ensure the new tyres do not wear prematurely or down to the cords again, as well as improved handling.

I do not mind spending probably over £100 on alignment adjustments as long as they are to the correct settings and I do not have to do it every few years.

Some good on here thanks for everyone who had replied.

I have checked my tyres and the fronts are wearing more on the inside, probably in line with the “Toe wear” on the chart on previous page.

I’ll get my new tyres in next week or so than find a place that does Hunter wheel alignment and go from there. Hopefully get it sorted.

Sorry been busy with work, so not been able to post here - this link is one I posted previously:

all wheel alignment

I have a 2018 ST Cupra which needs all wheel alignment. Its been checked on a Hawkeye and the front and one rear definitely needs adjusting. I have tried numerous tyre places, aftermarket businesses, VAG group dealers and they all say they can't do it as the car has the ADAS nanny state safety...

www.seatcupra.net

There are some links to the workshop manuals with the geometry settings - Note this only has the Standard Cupra ST (PR Code - G12) suspension settings, not the R ST. Technically the camber isn’t fully adjustable, but the workshop manual describes how the camber can be adjusted slightly by moving the sub-frame.

Just to add to this, my standard Cupra ST Conti tyres scrubbed exactly the same as this after 7k miles - had 4 wheel alignment and swapped to PS4S; now completed 19k miles on the current set and now at 3 mm.

Im also considering fitting these (https://www.racingline.com/subframe-alignment), and getting another 4 wheel alignment done at the next tyre change - I have hit a couple of sunken iron works at night recently.

Just heard back from another R ST owner on Facebook.

Again Toe was out causing inside wear.
His adjusting garage contacted Seat UK and it took them a week to get the correct values.

It would be helpful if you could post the figures they supply here

Maybe i'm missing something - not for the first time!
But looking at the PR codes for "Cupra ST R" I think a press car below:

Gives this data:

And this damper PR code:

This G12 PR code is in the workshop manual for running gear:

And this here although I’ve not fully worked out what it’s telling me

This one sits to me as being the correct one, the earlier one you posted is for a hatch I think as its rear camber was not mentioned as being tweaked...

Looking at the acceptable figures. the front toe and rear toe have a much wider acceptable range than the standard Cupra:

Front
Standard: 0°0' to 0°10' with 0°5' being the sweet spot.
Cupra R ST: 0°0' to 0°17' with 0°8' being the sweet spot.

Rear
Standard: -0°1' to 0°9' with 0°4' being the sweet spot.
Cupra R ST: 0°7' to 0°23' with 0°14' being the sweet spot.

Hi all

Thank you for your assistance. I still await the Seat dealer's feedback from Seat UK. I will update what they have to say.

I am not sure if Kwikfit or any other Hunter service provider will adjust or tweak to settings if they are not on their database.

 

[Slickric21]

Had some PS4S’s put on yesterday at F1Autocentre, they didn’t want to do the alignment as they were unsure about the negative camber.

I had the alignment done at a local tuner this morning and as expected the TOE was out.

The car did appear to be on the database, although the recommended values are again different to what we have seen so far.
Not sure to be pleased with this or not for £84

Hi all

Thank you for the update Ric.

I have still not had any news from Seat UK. I have chased the dealer several times and the now Service Manager is currently off with Covid and apparently, he was the only one able to deal with the query and potential warranty claim.

I went back to the local Kwikfit and asked them to check again that they had selected the settings for the correct model. They have now said that they had used the only settings that were on their Hunter database and although they previously told me they had double-checked the settings and that the database was always regularly updated, they have now said that it might not be up to date or include all models! So that has been a complete waste of time.

I have found another local Hunter specialist and they have confirmed that our model is on the database.

In the meantime, my car had its second-year service at a different Franchised dealership. A much better service experience to the other dealership. They managed to find the correct settings for our model, so I really do not understand why the other main dealer could not find the settings or tell me! Or even to tell me that they had to ask Seat UK for the settings.

I am unsure whether I can name these good or bad dealers on this forum.

Anyway, here is a copy of the specification from the other dealership - another VW group dealership, but not a Seat dealer, although the technicians all receive the same training, etc. I am not sure if it includes all the information required, but they were very helpful. They did comment that these settings are significantly different from all the other Leon models, including the five-door Cupra R. They are not able to do any tracking at their dealership and would just be subletting it, the same as the other dealership!

The dealer also commented that the settings are quite aggressive and would probably cause the front inside edges to wear significantly and prematurely anyway. So perhaps my car/our cars are set up correctly and will always wear out the inner edges prematurely and so possibly poorly specified by Seat for real-world driving, perhaps something to constantly watch out for in the future.

I will get the tracking checked at the other local specialist in the next week or so.

I have just compared these settings with those posted by SuperV8 on Tuesday.

The settings in the table he had provided show the G12 model, but not the ET8 version and the settings are very different.

The difference in the front camber for each side is quite significant to me. It maybe worth looking at those Racingline spacers to better fit the subframe.

Yeah I did notice that. It’s the same on the screenshot of the other R ST owner I posted also, front O/S camber only -1.5’.

Would that Racingline subframe kit definitely sort out that camber difference ? (If I can find someone who can fit this)

I’m half wondering if I should raise this with Seat as a warranty issue as it should be -2’ as advertised surely on the front, considering it can’t be adjusted ?

Alignment will be classed as wear and tear sadly.

Not sure if the Racingline kit will sort it. My understanding though is that the subframe is very "sloppy" in the amount of wiggle room it gives for fitting. Whether this is to speed the process up of assembling the car I don't know. However, I believe the kit is meant to reduce the tolerances and make it more central. So in theory, assuming everything is where it should be it should make an improvement. Downside is the cost and then another wheel alignment too.

If you were to do it, I'd also look at the Audi S3 Aluminium subframe swap as a weight saving improvement too.

I'm following this thread from the beginning, very interesting. I've requested SEAT NL for the official data. Request is received, the answer still has to come. When it does, I will report here.

About the Racingline fixation rings kit:
In theory fixation of the subframes should be a good thing, but you loose a (slight) adjustment option. What would be more important?
Also, could there be more road contact noise inside the cabin?
Are there any user reviews about this set?
