Grip Tyre Softener??

[tvrbob]

Is there any experience of this tyre grip enhancer? It claims to soften and thereby improve the adhesion of tyres. I have an aging set of Toyo TS-1's on my Chimaera and was considering using this on them for my next trackday.

I have used Grip tyre softener on Kart slicks with good results. I now treat used slicks (for trackdays) fitted on our Radical Clubsport. IMHO it does works and definitely extends the usable life of the tyres.

The blurb says that it can improve lap times etc. which I'm sure is possible but have not tested, I have used Grip to bring some old slicks back to life which it did with great results and would use it again and recommend it.
