our vega works consistent. 102" wheel base, four link, double adj rear shocks, stock a-arms with full drop. it does love the 50ft rear wheel leaves the best though. i can safely say the 60's generally are with-in a few thou all weekend. of coarse this is tracks with good prep but even still on the lesser tracks it does very well in my opinion, still with-in .010
this has took a season of finding the good settings.
years ago when i first started bracket racing those doing alot of winning were leaving on the back wheels. track's prep today are much better than 14 years ago, makes this thing called consistent even more user friendly to work with!!
