Just added Dinan Stage 2 - Traction Issues

[twin turbo]

I really do not want to purchase wider aftermarket wheels. Really like the gloss black 19's. Will going to a 285/295 with a softer compound solve my problem? I was one of the unlucky ones that got the Continentals when the Michelins were back ordered. I assume that is part of the problem. Any suggestions would be greatly appreciated. Thanks in advance.

Anything bigger than stock will help. I too was one with Continental and now run 265/35 305/30 Re-11 Traction is improved but still smoke it in first

I'm putting MPSC2s 265 front / 285 rear on my OEM 19s 1st week of June when I transfer my car out to SoCal. I am going with this since it was tested on the GTS albeit with a 20 inch in rear. I have not been convinced that wider PSS's will solve traction like it is stated in this thread (There is another thread on http://f80.bimmerpost.com/forums/sho....php?t=1088103).

I can only think MPSC2s will be a huge improvement over PSS, but 1st I believe will always be the bugger and you'll have to learn how to launch regardless of size and compound or even both. Additionally, if you go with a softer compound like I am you have to be willing to shell out for new rears every 5,000 miles is my experience and being careful in rain at the 4,500-5,000 mile mark where aquaplaning does occur, which I am completely fine with.

Not just wider, but stickier. With NT05R drag radials I can now launch in first, even launch control, but second and third still may spin depending on the surface.

Just getting 295/305/315 section tires isn't going to solve everything, unless you change the compound too.

Absolutely agree. I had 355 P zero's on my GTR and they still would not hook up at 550whp.

Really? I have 295 MPSS rears and stock size MPSS front on my GTR and traction is great. I have tune, mid pipe and filters, probably low 500s for WHP. Even in stock sizes the traction was very good as long as the tires were warm.

Whats your wheel and tire setup? I was thinking of going 305/35/19 NT05R drag radials on OEM 19's but im unsure if it will fit.

285/40/18 NT05R on 18x10 wheels. Hooks like a champ.

Keep in mind if you want your DRs to hook from a dig, they like lower pressures and warmer temps. You can't just roll out of the garage and launch it, you have to be set for success.

The compound wasn't very sticky at all, not good for traction at all.

I just went with some 265's up front and 295's in the rear and the car feels really planted, traction is definitely improved so far. You can change your compound, but you'll lose some tire life and performance in poor weather vs. the PSS. If this is your daily driver I would recommend going for a wider PSS. There's a huge thread in the Wheels and Tires section about bigger tires on the stock wheels. Head over there and check out some of the options people have gone with.

Anyone know the widest you can run on stock 18 inch wheels? I'd prefer to keep my stockers and just use a better (nitto)/ wider tire

I am considering going Dinan stage 2 as well and that is the one thing holding me from doing it right away. I got the right sound with MPE and am really enjoying the car as a DD. Do I really need more torque when I already spin the tires as is...

Don't get me wrong, the extra power is quite addictive. It's just aggravating when you get the occasional race and you can't hook for shit. Launch control is absolutely useless, even set at the lowest RPM. Highway pulls are much more fun however.

Get wider 19's and go 305 RE-71 in the rear. Helps out a ton but this car still is not good at getting power down.

I have Dinan stage 2 and 295 AD08s in the back. Traction is much better than stock tune and stock contis. I also have the Dinan coil overs, so don't know if that comes into play. I have noticed as temps rise in California, traction is amazing. Almost no wheel spin in second. Starting to wonder if power is dropping as well with rise in temps, at least enough to account for this.

Hi , was just browsing through , as an owner of a 2015 M4 , I can tell you
In the last 8 months of ownership, the m3/m4 (f80/f82) has some serious traction issues , the tyres being contis or PSS in the 275s are just overwhelmed
By the amount of torque , even in mdm mode, it's a world wide issues regardless
Of country and surface . So to get on with it , yes a 285 pilot cup 2 tyres at the rear will pretty much fix your issues up but you need minimum 25 degrees of heat in them, but 30-40 degrees is ideal epically if you take all the
Safety nets off believe me it grips pretty well , it will brake traction though
In first , you just need to learn to modulate the throttle . In saying this if you want too get great 0-100km times , forget launch control its f#####****k useless even with the 285 pilot cup 2 tyres it will hook up initially and then fry the tyres. If your model has the damper settings , set it in comfort mode so the car squats like a drag car , have the mdm mode on and your throttle and gear shift in the sport plus modes , you will need to obviously change gears your self . Tyre pressures should be according to manufacture specs no higher as the tyre gets to hard and when the
Car squats it does not flatten the tyre so less tyres surface on the road. With this
Method I have managed consistently 4.2 seconds , in from 25-40 degree heat and varying fuel loads 1/4 too half to full all on pulp 98 octane . Worth mentioning also I have a stage 1 tune with race filter and Akro exhaust , the exhaust by the way witch is Frim the cat back is only for noise , it has no benefit
Dyno figures
Stock 249kw
Tune 297 kW
Both figures at the rear wheels
The tune is only mild and it's given it mid range
Bottom end is unaffected.
Bottom line all rear will drive cars Are hard to extract the best especially turbocharged cars with so much torque early on , you just need to learn to control your throttle inputs . When I want maximum traction of the lights I always have the dampers set in comfort , around twisti bits , it sports or sports plus with fine throttle inputs so as to not let the rear step out . It's taken me lots of experimentation to get to that figure , mind you this times are in the public road not on a track , I reckon it will definitely go well under 4 seconds , but I have much given that up , it's just not worth it , and by the way the amg cars and many other rear drive cars suffer the some issue with traction , I have conversed with our major motoring magazines and the all agree , with traction and three silly launch control systems . Next time I'm buying an AWD
The never fail to get good launchs even my brothers Cla45 with a stage 1 tune
4.14 seconds (with launch control) to be precise , but useless on a rolling start it gets demolished by me . And another thing the 285 pilot cup 2 tyre fills the wall perfectly no need for spacers, if you go for a 295 or a 300 you will affect your speed ratio your speedometer will be off due to the tyre ration not the width but the height , the 285 maintains the some ratio but it's off by plus or minus 1-2km . Hope this help

I put RE-71s on the stock 19" rims. 285 in back and 265 in front. The RE-71s run much wider then the stock tires. You might be able to get 295 in there but 285 looks great and traction is HUGELY improved.

So did you go with a 285/30? Is the tire fairly safe in rain? I commute 100 miles a day in South Florida, rains constantly. Thanks in advance.
