Picking up the new wrx on Friday...can't wait...wanted one for ages.

I was planning on using Ultraseal in the tyres, i know it's good stuff as I've had it in all of my bikes.

The supplier tells me that there is a potential problem with low profile tyres as they have a lateral rib inside and the ultraseal can collect here and cause out of balance.

They reckon that some people have used it in 45 profiles without a problem, but won't guarantee it.

Has anyone used it in their wrx ? I'd appreciate any comments.

Cheers
