my RT12 (which as you know basically has a 996 TT drivetrain) has started to pull slightly to the left under hard acceleration in 2nd and 3rd gear.

its just for a split second-- only come in just as the boost comes in-- and then its gone. but its enough to have to be conscious of it and be ready to keep the car straight as the power kicks in.

once past that initial kick, everything is normal. tracks straight, brakes straight, no problem at high speed.

have reproduced the symptoms several times, always on perfectly dry, clean, flat, straight roads. tire pressures are all normal, so my guess is its the wheel alignment, which i'm having checked very soon.

any other ideas what this could be?

 

First thought, alignment.
If that doesn't fix it, diffs might be out of spec due to wear?

 

another suggestion that makes sense to me is a bad/cracked suspension bushing or engine mount, causing drivetrain twist under hard acceleration...

definitely worth a look!
