PS2's....

[K1_MBR]

had some PS2's fitted on sat..struggled with traction ever since...had 275/30/19s fitted...what pressures should I be running? is there a bedding in period?

[DazBlackCSL]

Run the standard 265 / 235 set up on pressures, should be on the inside of the door panel..

Should not upset the traction though?? Seems strange

What you running on the fronts, have you gone up to 245 to balance it?

[K1_MBR]

not on 245 at the front as these were fitted new when I got the car in dec...

thinking they just want scrubbing in....not really gone far so reckon its just a wear in period. going to place it in track mode and give it some grief on the way home to scrub em slightly....

:thumbs:

That may sort it !! :-D

[K1_MBR]

"yes officer...i was just trying to bed the tyres in, thats why I hit that corner on the wrong side of the road at 90mph...."

works every time :beer:

[DazBlackCSL]

:whistle:

lol !

[K1_MBR]

that didnt work...can be quite scary as its not keeping the car in a straight line! Think the balancing might be out as tyre pressure light came on when driving home...going to take it in this week for re-balancing....

[DazBlackCSL]

Don't worry about the tyre pressure light, we had it on whilst driving through Europe almost constantly at high speeds, and all was OK , got back checked it all out and think it just comes on if your pushing it!

Don't sound right though, balancing wouldn't cause the loss of traction ... could be the bigger size rears and normal fronts ??

[K1_MBR]

you think so?

I wouldnt have thought it would have made a difference. Its as if the car feels unstable....the previous owner had 265/30 19 on, which arent correct as it should have been 265/35 should it not?

[DazBlackCSL]

Actually thinking about it, it might be the rear trailing arm bushes, as you've just changed the set up ... reckon 99% thats it, just had mine done under warranty and much more sorted... does it wobble when changing gear when your on it ??

:thumbs:

[K1_MBR]

yes it does...especially on full beans when coming out of a corner. going to try the balancing act first though....or could it really be the RTAB's which are causing it to wobble just from a tyre size change?

sorry if I sound thick, just would put it down to something simple like balancing issue normally!

and I've not got Bee Emm warranty....although good mates with the service manager at Sytner High Wycombe....whats my chances of goodwill?

[DazBlackCSL]

Its def RTAB's not that expensive actually.... especially if you know someone, don't reckon they will go for goodwill tho ... worth a go, but I bet you a beer its them, and you will be 100% sorted when there done :beer:

[DazBlackCSL]

A mate of mine works at Sytner - Ascot and will do it privately if you have no Joy ...

[K1_MBR]

thanks for that Daz....would never have thought that the tyre change would do that. I'll get Cameron to take a look at it one day this week.

If you were local I'd shout you that beer!

[DazBlackCSL]

No worries... poss at the ring after a track day in the future :wink:

[K1_MBR]

ordered some powerflex ones from my mate Steve at www.carperformancepartsuk.com - will be here tomorrow and fitted tuesday! :beer:

[K1_MBR]

managed to get BMW goodwill on the RTAB's and a front wheel bearing which is shot. Also having new ABS sensors and the handbrake sorting. BMW even doing a labour contribution!

So I got a pair of powerflex RTAB's if anyone wants them?

[DazBlackCSL]

Good work, some of them are OK .... bet it feels totally different now its all sorted ??

Next Step a Fast Road Geo set up from Thorney MSport !! :wink:

[K1_MBR]

get it back thurs night / fri morning depending if I can get to pick it up thursday night or not. Had a full geo on it just after i bought it, so they are going to do a full wheel alignment on it too!

Handy knowing the service manager you know :beer:
