Got a buddy that's interested in getting some coilovers, budget is no more than $1k, any recommendations?

 

I have B&G RS2 coilovers I got from P-tuning, no problems with them so far, car handles beautifully. Been on for 9 months now.

For less than $1k, I would roll with Tein Street Basis. Can't go wrong with Tein. I also have them in stock and ready to ship BTW.

You still will have funds left over for more suspension mods like a new rear sway.
