So your riding the clutch and making it slip

have you got something like a Wärtsilä-Sulzer RTA96-C engine fitted?
that has 5,608,310 lb·ft @ 102 rpm, that would get the wheels spinning

but at 1100rpm your engine will produce about 100lb.ft of torque, not a chance of spinning the wheels

show me a non-diesel 4-pot subaru that makes 100lb/ft torque at 1100rpm! Less than half of that more like...

Sounds like my M135i !!

It's not snowing where you are is it?

I used to have trouble getting my Spec D running over 330PS and 470Nm to lose traction in the wet when pulling away.

One thing I would add however, is that the original PPP map was extremely sensitive at low throttle settings and needed more revs than you would normally expect to be able to pull away without stalling.

Even my previous Classic (280PS) only spun the wheels briefly in the wet after side stepping the clutch at 4-5000 ish revs.

Something very wrong - but I guess you know that.

It was a guess, sorry Einstein
Stuey said it was 270bhp, I was just meaning that figure was irrelevent and torque would be substantially lower

I have to do something really bad to get my fwd RCZ R to wheel spin in the dry

OP, check the tyre pressures to start with before doing anything else.

Doing a bit more investigation.. Wheelspin kicks in at 1100 RPM in first. Let me put it into context, I got overtaken by a Yaris whilst trying to start without wheelspinning
So the mechanic at the garage drove it and there wasn't a problem, and your getting wheel spin at 1100 rpm?
Surely the problem would of been seen by the mechanic if it's happening at such low rpm.
That doesnt make sense, 1100-1500 rpm is basically just pulling away normally.

Sure you not getting wheel spin confused with something else?

have you had the wheel alignment checked? when I got my bug the alignment was all over the shop - particularly at the rear end. Car drove like a RWD it was really difficult to take off and keep a straight line or hold a corner.

Following a proper 4 wheel geo setup it was on rails if your car's a 2.5 they should be able to slow the throttle pedal down a bit which might help - could it be you just have heavy feet?
