Well for one thing you have o ring tires there's no give or flex on those side walls.

 

Yes, lower profile tires will make for a little more rough ride, and you could replace all the bushings with rubber polly everywhere will increase stiffness and bind, other than that the spring rates also will make a difference. New struts/shocks would help depending on if you get performance ones, or plain jane softer ones for a stiffer or softer ride.
Stickies at the top have info on shock/strut combo's, and affects of rubber/poly bushings and rod ends.

 

any specific parts you guys would recommend??

 

Switch rims and tires with your brothers and take it for a ride see how it rids and then try to convince your brother to give you back your old rims a tires.

 

A quick & easy solution to see if its the tires or not.

 

yeah i dont think id be able to get my rims back i owe him 450 bucks right now....

 

Money Pit has the Smart answer. There are sooooo many variables, so he's spot on. Who knows; he could be riding around with only 15-17 psi air pressure in his tyres.... Nitro
