I was thinking about putting 20S www.dtmautowerks.com and wanted to know what type (if any) long term affects it will have on my suspension should i go with 19s.? I want to make sure that I have a smooth ride but want to fill the well. how bout tires and then how do people lower there cars an inch i heard they just use a computer. big change from back in the kyb days. thanks

 

20 inch on the S55 ? No problem. I would go with the TOYO T1R , awesome tire, we use them all the time. Yyou can lower the car by switcing out the links on it.
