I know it's a little late but I'd say it was a waste of money. I'm competitve with my Slash and it's not LCG. I have
-STRC ALuminum Shock Towers
-Proline Shocks
-Tekin 17.5 w/Tekin RS ESC
-RPM Rear Arms(don't recommend but better than stock)
-Different tires for different tracks
-STRC Caster Blocks(not really necessary)
All that and I was 2nd fastest qualifier in stock SC on our 1/8th scale track. This setup gives you all the adjustability you need, and other than the towers, I bought everything used off of here, for a total of ~$125+$100 for the truck itself. Not too bad IMO.
