    Turn TC off, that should stop the bogging down as itís due to that system detecting wheel spin even if itís not showing on the dash light, thatís for regular launches.
    For launch control you need to disable TC also for it to launch properly, It may not even be in LC mode if you leave TC on.

    Tyres will only cure spin in TC mode on if the grip exceeds the power levels, dare say youíll always get it with TC on.

    Curious to see what 265s look on a 8.5, maybe, just maybe itíll be close to perfectly balanced for understeer.
    Let us know and enjoy.

    Had it for a month now, never had traction light came up since..
    thanks, appreciate the feedback. Can you go for this squared up set up on the stock rims? assume so.

    Yes, rims are the same front and rear. If you push the car youíll just get more understeer at cornering limits with this square setup.
    If PS4S 245s are gripper than 255 P-Zeros, then the limits are raised.

    All good if youíre not slamming it through corners but balanced traction is something that can save you from a wreck at the absolute limit.

    Rims are not same front and rear! front is an 8.5 inch rim and rear is 8.0 if the car was ordered with the staggered setup (99% of cars i believe?) - that being said this is not an issue for a 245/35 all round.

    I donít have an RS3, & Iím sure the haldex set up in the RS3 is better than the S3, I recently lost drive to my rear axle. They changed out the pump, the clutch pack & updated the software & it still had no drive to the rear. They couldnít find the problem. Got them to put my old haldex pump & clutch pack back in and everything worked fine? That was 8 weeks ago & everythingís been great since. My point - Iíve been told the gen5 haldex systems sends 10% of drive to the rear axle all the time. Once slipis detected, drive is increased to the rear to compensate for slip at the front. On gen4 & below 100% went to the front axle, 0% to the rear until traction was lost. The constant 10% drag on the rear axle / clutch pack seems to be the reason for haldex problems on S3/Golf Rís. The minor drag causes the clutch packs to ware, this clogs the filter which reduces oil flow within the pump, which results in pump failure. It may be compounded by aftermarket tyre diameter differences on the RS3ís, or it may justbe an excuse Audi uses for to fob off RS3 owners.

    Good idea to replace the haldex fluid and flush the haldex filter clean at each service interval, itís not an expensive task and not much fluid required, will keep things in order.

    Hi all,

    About to change tyres on my RS3 & just wondering if those of you that changed to the MPS4S 245/35 all round are still happy with the choice?

    Thanks,

    Michael

    Yes very happy with it, no traction light came up since, i think 9/10 RS3 owners who changed the stock tyres went with PS4S
