As we want to be able to drive the Corrado to the track, any tryes need to be road legal. I have little/no knowledge of what is best for the track, so what tyres are the best for track use? What about brake pads? Again, they don't need to be superb on the road, but of course good on the track. Would Ferodo DS2500 be track worthy? What about EBC red-stuff? Any ...

He said that it increased compression ratio by 0.5, and that led to an improvement in torque.

As far as I know the late US VR6s got a plastic inlet manifold with variable geometry, much like the R32s and 24Vs. Now, this should be retrofittable to the older VRs, I assume they just need an adaptor for the throttle body, and a little bit of piping making up?

Does anyone know anything about these?

I just bought a new set of spark plugs for the VR, looked at various options and decided on the recommended BKR5EKUP ones, which have platinum tips, now I could have bought the normal ones, or the iridium versions, but I wasn't entirely sure, and as I won't be changing them for some time, I thought I'd spend the extra £20.

Was fiddling with both Fay's and my VR today, and while looking at the measuring blocks, I noticed that my idle adaption was above 1, somewhere near 1.18, but Fay's was below 1, about 0.95 or something.

Now I know that 1 is stoich, i.e. AFR 14.7:1, so, an adaption value of above 1 indicates that the car is running rich, and below 1 it's running lean.

I.e. above 1, it may have an air leak after the MAF?
