BMW and M Power Owners

As above I would absolutely, 100% be asking for the modified suspension to be covered in writing. Although Ohlins is very good stuff all it would take is a blown seal and a replacement or refurbishment would be hundreds if not £1k+ for a new set. A salesman's word ain't worth **** unless it's in writing. On dealership notated paper. Dated and signed.
 
I’d be weary if keeping the car for longer, as the insured warranty won’t cover Ohlins if you do get it after a year. Loads of M2s about, find another if it is a concern.

It makes absolutely no sense that the mid range tyre would offer better grip than the uhp tyre. It's the entire point of the Pilot Sport 4 range?
I have Pilot Sport 4 on one car and Primacy on the other...
It's pretty noticeable when accelerating quickly.

But think about it logically. Why would it be the case that the Primacy offers better grip than the Pilot Sport?

The Primacy is a mid range Michelin tyre designed for regular cars, not performance cars. The Pilot Sport 4 range is designed for performance cars - it literally prioritises things like grip and feel over things that are perhaps more important on the mid range tyre like fuel efficiency and life span. Both are made and designed by the same manufacturer to fit into different parts of the market.

Lets look at what Michelin say about each tyre:

The MICHELIN Primacy 4 tyre is designed for safety made to last[1] while being one of the leading tyres for longevity in its category


One of the leading tyres for longevity in its category.
• Greater fuel efficiency[5] and 20% more mileage than previous generation
• MICHELIN's premium summer tyre for everyday performance: commuting or long family journeys

The MICHELIN Pilot Sport 4 S road and occasional track tyre for drivers who expect excellent grip, steering precision and control, even at high speed

  • MICHELIN's max ultra-high performance, summer road and occasional track tyre
  • High levels of reactivity and steering precision
  • Excellent road handling and control even at high speed
  • Excellent dry grip and wet braking performance

I mean come on - one talks about fuel economy and tyre life, the other is clearly designed for ultimate grip at the expense of things like tyre life.


I guess only you know what you've experienced but you have to admit it's a strange finding, right? Why would the tyre they designed to for going shopping in a Ford Focus offer better grip than the tyre they designed for fitting to a performance car?

I have absolutely no bias here - I have both of these tyres on my cars - the Primacy and the Pilot Sport... it would be great of the Primacy really was better than the Pilot Sport as its cheaper :D

I have to wonder whether what you are really experiencing is the difference between a worn tyre and a new tyre. Otherwise why would you have been in a position to be able to directly compare them with the same sort of wear levels etc? How did you even get to the point where you've bought a set of Primacy for a 128Ti anyway? Why did you pick them over Pilot Sport 4 (Or a similar tyre from someone else)?

There is of course nothing wrong with a Primacy. It's an excellent tyre and you can probably make a case for fitting them to a 128Ti. But that case wouldn't and shouldn't include 'because it offers superior grip to the Pilot Sport 4 range'.

So I am currently concerned and somewhat disappointed, opinions please...!

My understanding is that a car doesn't necessarily have to be totally standard, but it seems like its a world of confusion regarding what happens if something were to go wrong.

Personally I would not want one that was modified in this way.

Unless it happened to be modifications that you were going to make anyway - in which case you have some sort of additional warm and fuzzy feeling vs totally setting fire to your warranty anyway.

Given warranty is a primary concern here, I would walk away.
 
Thank you guys, yes, warranty is a major concern and I want it intact long term.

I have spoken to a rep at BMW UK who advised they wouldn't buy the car themselves...

I am putting these points to the dealer.
 
The way I see it, they almost certainly wouldn't replace a wear item like a damper anyway, aftermarket or not. I'd be happy to have an ohlins setup on the car personally.

Why not? Wear and tear is specifically and explicitly included except for obvious consumables.

The Primacy is in the same price bracket as the Pilot Sport, I didn't think it was mid range. Yes i don't deny it doesn't really make sense based on the descriptions but the torque steer is definitely not as pronounced with these tyres. I guess it is a little tricky to remember exactly how it was when i first got the car though but it was pretty flighty. I went for the Primacy as i saw someone on a 128ti group recommend them after replacing the Pilot Sports.

You're probably just more used to the torque steer now ;)
 
I don't know, to me a damper is an obvious consumable.

It's not a consumable at all let alone an obvious one! A brake pad or a tyre is a consumable, a damper isn't. It's certainly a part that is very much more subject to wear and tear than, say, a window switch but that doesn't make a consumable. There is no replacement interval and most people will never have to replace one. I've only once in 20 years replaced dampers on a car and even then it was only the rear ones.

I think you're confusing parts that wear over time with consumables. Not all parts that wear over time are consumable items which is why there is specific provision within the policy for wear and tear.
 
Just had a look around Joe Achilles' previous rear wheel drive M3 while waiting for my service. These definitely look much better up close in person! Grills are actually nice
 
Thank you for the replies guys.

I've got my deposit back, despite the garage insisting it's all fine and they'd cover it under 'good will'. This completely contradicts what BMW UK said, as well as BMW Warranty who deal with the extended warranties after the first 3 years are up.

I'm not sure they should even be selling it when the entire suspension system is heavily modified. For starters the new owner would need to be aware for insurance purposes, if nothing else.

A very strange situation...

Looking around BMW Croydon there seems to be quite a few approved used cars with modified bits on them! Also quite funny - just heard an M5 roar into life with an obviously modified exhaust, and saw a little old lady driving off in it :cry:
