New here, thought I would share my new wheel/tire combo.
I've installed Eibach lowering springs, new Koni Excel-G struts and shocks, and upgraded the entire front suspension with Moog Problem Solver parts: tie-rod end-links, inner and outer tie-rod ends, along with Moog's heavy duty lower control arms. I also installed Prothane 25mm poly sway bar bushings, a new TTR rear sway bar, and 18"x8.5" Monte Titano MT21 drop-forged wheels with Lexani 235/40R18 rubber. Ride is on the firm side with this combo, but still acceptable by my standards.
My 83K HHR 2LT one-owner, as bought:
Pics with new Eibach lowering springs with new wheels/tires, body de-badged and factory pinstripe removed. Springs have since settled a bit since these pictures were taken:
Next up for looks... darker tint for the front windows and continuing with a tasteful yet subtle black-out treatment, including a new grill, Depot headlights, black door handles, tinted marker lights, LED tail lights. Etc...
I'm very pleased with my HHR as a daily driver, I am very glad a bought one. I like it a lot! It fits my lifestyle and needs perfectly.
