The modern tyres such a the 175/60 x 13 Yoko A048R I use now are far superior but for a traditional profile tire on an Elan the XAS FF is great if you don't do a lot of miles as the cost is high and the wear rate high also
The Dave Bean Spring Rates and bars are versus standard as follows:
Standard - 0.688 inch bar and 75 lb/in Front , 68 lb/in Rear spring rates.
High performance road - 0.750 inch bar ( you can use standard plus 2 bushes) and 115 lb/in Front and 95 ln/in Rear ( I tried these but ended up with a 7/8th bar when the car was still regularly used on the road still)
Road race - 1 inch bar and 160 lb/in Front and 125lb/in Rear ( I use these rates but with a 7/8th bar for my Elan these days as it is basically a track only car, you can use them on the road but it does get a bit harsh!)
TTR's fast road spring rates will be similar to the DB high performance road and a 13/16th inch bar from TTR or 3/4 inch bar from DB is getting down to personal preference. I ended up with a 7/8th bar when the car was still set up for the road as well a sprints and hill climbs as in this situation I personally prefer a car a little softer on the springs but with a stiffer front roll bar given the state of our roads and tracks here in Australia.

Thanks Rohan! I think I'll start with the TTR ARB and see where that takes me. British roads are in a fine state of repair...cough, cough.
