I run the RB5 SP2,the vega is the best car iv ever run,iv been running mine indoor on carpet for 3 weeks,i ran it at the the f3,4,5 out door,all i changed was the wheel base,had i not been told by the man on the mic how well i was doing i would have been in the top 10

..........im just starting to push the car and it just eats up what you throw at it,im still running the kit RB5 springs and just a bit of lead under the speedo,i dont know who said they are no good in the wet,mine was awsome,but then i did have a L**I 22
