Contemplating on changing up my Rustler VXL.

I run on my backyard rc track. Not a real big track....23 second laps times with two jumps...and sandy. (Florida)
Have 2.8 Badlands at moment...love those tires. Titan shock shafts....aluminum caps with 40 all around in shocks.
Have ....can't remember what the weight was....but have two 1/4 nuts and bolts with 4 .......1/2 washers up front on bumper for weighted front end. (Sounds ugly...but really looks like two off road lights...lol)
Strc aluminum blocks...and everything else rpm plastic......oh....and HR all aluminum transmission case.

Anyhow....I'm pretty happy with performance. ...but just wondering if changing to a slash with the lcg kit if I could get better performance. .....plus just for a change

What would I notice different in the performance. ...good....bad...???
And I guess I would have to change tires?
Mainly. ..just don't know what to expect or what difference I would see?
