Newbie Question

[M4lifestyle]

Just picked up my F82 this week so hope you guys can assist with the questions i have. Understood might have been discussed somewhere but I hope to consolidate the info in here:

1- any of you done a 3m wrap for bumper? Does it really protect the paint from stone chips? And how much roughly?

2- what is the best bang for the buck for the exhaust. Dont care about hp gain but no hp lost tho.

3- have any of you bought the lowering springs and drove it in winter? I dont want to spend a fortune as I dont go to track. Whats your feedback on springs only?

4- wheel spacer, any negative feedback on them? Will that kill you bottom part of your rear bumper? Since the wheels stick out more?

5- for those of you who drove the f82 in winter, how was it? Would you not recommanded it? Im in toronto btw

Appreciate all, newbie here so if my questions here are common sense please forgive me.

I drive my M4 all year round, commute btw Burlington and downtown Toronto and as a precaution wrapped the entire front in xpel film. Its holding up well and saved a bumper repaint recently when a handful of roof shingles flew off a truck and hit the bumper. Just replaced the film and it looked new again.

In the winter, a square set up with good snows and you will be fine....

[M4lifestyle]

Oh waoh you did the whole front end! Thats including hood, fender, bumper ?

[jwortley]

Yes, I didn't want to see the line across the hood and frankly, my luck would be I'd get a bunch of chips an inch beyond the wrap...

[CanAutM3]

1- Not me, and I track my cars quite extensively. I could not care less for a few chips on the front end.

2- I went the MPE route for the exhaust. Not the best bang for the buck, but I like the fact that it is OEM, fully warrantied for the longest between matching the vehicle or two years, no hassle purchase and install at the dealer, 17lb weight reduction and it sounds awesome. I just got mine replaced with a brand new unit under warranty after almost 4-years (it was cracked), no questions asked.

3- I have Eibach springs on my car and I drive it year round. No major issues. But the car can bottom out during large snow falls.

4- Wheel spacers alter the suspension geometry and tuning as well as the scrub radius and required Ackerman angle on the front wheels. So they are not ideal from handling stand point. If you care more about looks than performance, than they are OK.

5- I've been driving M3/4s year round for 17 years without any major issue. I only got stock once with my E92 in a rather heavy wet snow fall; that's it. You just need to get used the RWD walzing. I find ///Ms are a hoot to drive in the snow

Thanks for the great advice.
I too was thinking about spacers but I was worried about negative
Effect on suspension.

For the exhaust I have the exhaust valve control’er
Essential for the downshifts.

But is there a 1000$ ish exhaust upgrade

I don’t feel like spending 3k and up for an exhaust.

What about resonator delete?

I currently run a stock exhaust with no performance pack

Thanks guys!! Appreciated the answers.

For just using lowering springs, did you guys feel handling got worst or its close to stock handling?

It depends what springs you install. I have the Eibach that I installed jointly with GC camber plates and it did improve the handling of my non-CP M4. They offer a moderate drop and increase in spring rate vs the base OE springs. If you have a CP, be aware that the Eibach will give you lower spring rates. IMO, some lowering springs are just too stiff and deteriorate handling because the stock dampers cannot cope with the increased spring rate. I find a good option is the M-Performance HAS. They are a bit costlier, but are specifically designed by BMW ///M for the M3/4 with adaptive suspension, so you are assured of improved handling plus you get full factory warranty. I will be installing these on my CS when I get it this summer.

Thanks. What is CP standa for and what is ZCP stands for?

I prefer to use the CP acronym to designate the Competition Package because it is internationally valid. Different countries use different option codes for the CP. ZCP is the USA option code for the competition package. In Canada, the option code for the competition package is ZHP. Ironically, the ZCP option code is also used in Canada, but it is used for the M4 convertible M-Performance Carbon Package.

Went with the MP HAS on my 2017 CP and did not notice any change in ride quality when at recommend drop levels; when I first got it back the car was sitting at lower than factory recommended levels and it was 'bouncier' and stiffer, ( not nice ) but flatter on tight corners. Handling is better with the MP HAS and of course it can be raised a little in winter if there were a need.

How much are the mp has go for? I searched and seems they are almost 2k cad.

[fil3]

i Just brought my F80 Jan 2018. drove winter already feel great. btw i m toronto too.

1. Do ceramic pro for the whole car.
2. You looking for sound i believe. If low cost you can choose value deletion kit. (or unplug the cable) so you don't need to turn on sport mode to open all 4 values of the exhaust.
3. lowering spring should be H&R. heard it give a good drop fitment. I am looking into this since i havn't change spring yet.
4. front 12mm rear 10mm
5. square snow tire, turn MDM traction on . you should be flying.

yup there are also new bolts and nuts required ($124) on top of the MP HAS kit price ~ 2k, plus installation...~600-1200, depending where you go...

Only one I would reconsider. Much better options now in Swifts and Eibachs.

Thats a little too much for what I wanna spent so guess will go with h&r or eibach eventually. For outlook I think h&r drop slightly more than eibach i believe.

Thanks for the details!

Ceramic pro would be as good as xpel? Anyone has experience?

For the exhaust I am afraid even sport + mods isnt lourd enough for me. I want something lourder

Eibach is really conservative. .8/.4 inch all around.
H&R drops way too low and it fks your shocks eventually.
Go Swift or ED. Or MP or KW HAS for ~500 more used.

I’m on Swift.

Ceramic Pro is a coating - it helps with shine and preventing scratches from washing. It won't save you from rock chips or deliberate abuse.

Don't do MP HAS if you want more of a drop....
Just springs will be cheaper, no question, I thought about the Eibach's springs too, they look good.

That looks quite a lot of a drop? What is the exact measurement of the drop?

Did you do the alignment after drop it? Any camber changes needed etc?

Yes springs and just basically need to choose one I wont get myself stuck in winter.
