All except A8_Tony's. As long as the rolling diameter is the same 18's / 20's won't make any difference. If however Darrens on 245/45s and your on 265/35s then he will have a wee advantage.

Ok now I see the RT isn't taken into consideration on the total, I was thinking you sat at the line for 2.5 secs and still managed a 14.7 makes sense looking at the speed :o

Oh and Mike's RT is pretty good.............................................. ........................for an old man:D

Yeah, on my fastest run I was on my own on the track, so could wait for a couple of secs to make sure I launched OK. Its the ET and Speed that counts. If I'm paying attention my reaction time is usually about 0.5 sec.

jethro we will have to look at the different size in wheels when we meet. the only other difference i know of is that one of my cats was not standard and maybe allowing the engine to run more freely. i have now changed it to a standard cat. i did notice that all the runs i had that everybody got off the line before me and i did not catch up till a good way down the straight.

Mine wasn't - just a lowly A8 4.2 QS (3rd from the top)+++
