Losi 22 advice

[rc10andy]

Hi, ive previously mentioned im just starting out again in RC, im just wondering if a brushless Losi 22 ready to run would get me away at club level?

Also if anyone can answer these-

Whats the difference between the RTR and a normal kit Losi 22? I know the obvious like no motor, esc and radio gear. Are the shocks different? Tub different?

Alsoshould i buy the losi 22 rtr could i add upgraded bits as bits wear o break?

Thanks for any answers
