B4 newbie - understeer & some other q's

[Hallsy]

Got my new (to me) B4 yesterday, as far as I can tell (newbie) it's totally stock apart from RPM front turnbuckles.

Took it out for a quick run in a local lorry park yesterday, running a lipo and spiked tyres. It seemed to understeer a lot more than I'd expect, getting worse under power. Is this normal for a B4, or a sign that I need to add some front end weight (due to the lipo?)?

Judging by how quickly the rear tyres have worn, I'm guessing that I might not have had much front end grip on the slightly damp paving with spiked tyres. Looks like I might have to get another set of wheels depending on what surface we're running on!!

Other question, the buggy is in good condition, but having been raced a few times I noticed some play in the suspension mounts and front A arms. With the shock mounts, will this likely be remedied just with new bushings, or do the eyes & bushings tend to wear together? Likeiwse, if I have some play at the A-arm mount, is this a sign that the arm itself is worn (just runs on a pin - right?).

Or is it normal for there to be a small amount of play, even with new parts?

Was great fun nontheless, until my gf managed to break the rear shock tower!!! Nevermind!
