Well I ran my buggy on the track for first time yesterday. All I can say is WOW. I ran stock springs 35 oil front 30 rear and 7000 center diff. The car with a 1900 tekin and rx8 with no tweaking was the fastest thing on the straight away. It jumps extremely well and effortless to control in the air. The only thing was the rear end wanted to spin relatively easy. Any advice is very welcome to help with the rear. In my opinion this buggy is the best I have driven yet and it's my 5th this year lol
