MarkCup's BMW M140i

Having spoken to my mate in work yesterday with a JB4'd M135i he says they are utterly useless in this cold, wet weather, even at quarter throttle the car is all over the place. From a standing start in similar conditions he said you cannot get any traction what so ever and it just snakes about even with decent tyres on. I think he's regretting selling his 250 cup for it.
He must drive like a prick 24/7

Not sure? Is that any different from any fast and cheap car though? Nob ends buy them and wrap them round lamp posts.



Yes and no. There is plenty of traction (genuinely, I did 0-100 in a tad over 10 seconds) in the wet with PSS tyres. PS4 are on another level in the wet so those would be what I’d recommend.

If you drive with DSC off then the back will go from time to time, but isn’t that the point of driving a powerful RWD car?

I wouldn’t recommend my mum drives around with a JB4 and stability control turned off, but my GF managed just fine through last winter the times she drove it. Just stick it in auto and relax. It’s only when you start giving it bootfuls round corners that it’ll bite.

I love the 250 shape Megane but not a hope in hell I’d trade a 400hp RWD weapon for one.

Std?
0-100 in how much over 10 in the wet!?
Best m140i quarter mile I have seen at pod is 12.4 @ approx 112ish dry days seen a lot run too. That's a good time in standard car.

I found my M135i fine in the wet, you just drive to the conditions as per any other car, well barring the RS3, irrespective of the conditions that thing was ballistic lol ... on the flipside, i found the MPSS to be absolutely useless in the greasy conditions post rain. Actual water on the ground fine, dying out, but not dry yet? Death-trap 😂
The newer PS4S are a billion times better in those types of conditions.

I have said in the past that the rave launch reviews & lap times for the M135i would very much have been tyre related. If it came on Bridgestones/Pirellis etc from the factory it would have been panned as an absolute mess of too much power & no traction.

Unless they are brand new, they are absolute turd; its what the RS3 came on when i bought it.

Swop them out & the car will be transformed. On anything high powered/RWD, there is no reason not to fit PS4S these days.
My mini has them fitted currently. I honestly think I've had budgets handle rain better. They are terrible for a "premium" tyre.

If you've got a M140I there is, as there not made in 18"
lol. Sad times. You want PS4 then. Just fitted another set to Sarah's TT (its had nothing but Pilot Sports for the past 10 years). I'd wager that on the road they are probably just about as good, with more than likely slightly better wet weather performance. Wont be as good on track, or in super dry conditions, but still better than most tyres out there.
 
Ahh right.

PS4's are probably just as good.
PS4s are incredible.

Albeit the car didn’t have a JB4 on at the time, but in the M135i I used launch control with PS4s and it felt like it was AWD the way it launched (it was only a couple of months ago at around midnight so it was very cold, but on the M6 toll at a booth so was at least dry).

Prior to that, with PSS, the car would do a burnout if you activated launch control on anything other than a hot day with warm tyres.

Anecdotal for sure, but it’s hard to stress just what a difference in normal weather grip there is between PSS and PS4.

My experience has been much the same. Cheaper than PSS too. Absolutely awesome tire.

I'm proper balls deep in looking at M135i's at the moment for late next year... Like signing up for a forum balls deep and watching youtube vids for 2 hours. Says a lot for me as I still couldn't find something to commit money too, that's why I've had the Megane for 8 years!!!

I'm running Bridgestone Potenza S001 and mine's not skittish in the wet at all. I'll be on PSS or PS4 next, that they're cheaper than anything on the RS is a bonus. Regardless of conditions you can pitch the 140 in just like the RS or ST, it takes a little longer to settle and the back only moves if you ask it to. Get it loaded up and it's linked to the throttle and almost linear. With the diff it's going to be epic.

Speaking of which I'm not going to fit that for a while. The plan is to book two days at Goodwood four weeks apart and get the diff fitted in between so I can feel how the open versus locking diffs change it on track.

I think you’re mad for sacrificing all this practice time in the damp, but one things for sure - a B2B comparison video of diff vs proper diff will be a good video indeed!

Especially going from open diff to locking diff and taking it on track within weeks of fitting.

Remember to invite me along and you can stick a GoPro to the front of mine and I’ll get a few shots from behind.

The Yokohama can definetly take a bit more abuse than the Michelin on track but overall grip levels arn't massively bigger


I stuck SOME PS4s on my road wheels recently to replace AD08Rs that I've ran for years and they are leagues ahead on the road.

I've been really leaning on the Bridgestones this weekend, they hang on well! I'd like them gone before I do a trackday in the new year so I can get some Michelin PSS or PS4S on it.

In other news I almost went around completely larking about in it earlier, all super slow <20mph stuff, it's hilarious fun trying to keep the back out there.
