Geesh! If ppl don't like zuki's, why do they even come in and post a reply?!
Anyways,
To the topic starter, you are thinking correct. Get suspension first. It's the fastest thing you can do at this point. I'd recommend PEP's over Elka's personally.

TC Racing or Yoshi for motor work. They can advise as to the best motor FOR YOU!

Ppl, please don't argue with others that don't care to post on topic or are argumental. This is one of the most proffetional forums out there and lets keep it that way.
Simply report it to a moderator.
