so i finally decided to get some coilovers in the next few weeks. Im deciding on going with BC. i have a 2011 G37X and i had a few noobie questions. i don't plan on slamming the car but i do want to lower it to kill the wheel gap. BC gives you the option of extreme low and when i asked them what the difference between the extreme low and regular they didn't have much to say. so can someone please tell me. also what spring rate is recommended and what do the rear extenders do. lastly is the swift spring upgrade with an extra $350. plz help guys

 

I'd look at the KSports too.

 

I'm getting the Fortune Auto 500 Coilovers for the G37X AWD Sedan. There are plenty of good reviews on this site. Get it with the swift spring upgrade. As for ride quality, I heard these coilovers are the best. For the best price contact LUKE at THmotorSports...

I have the Ksport true type coilovers, plenty of adjusability and comfortable ride for a daily driver (G37xS sedan). Not a bad price point either, less than $900 new.

 

Do you have k sport and how is your ride quality ?

 

your car looks great that's how I want to be sitting how long have you had ksport and what's your spring rate

 

I've had them since October 2015 and driven about 3,000 miles. Ride quality is great, may be too bouncy for some, but there's plenty of adjustability to make them softer or stiffer. Being as low as I am, there had to be some sacrifice made in ride quality but it's still surprisingly smooth for a daily driver. According to the Ksport website, spring rates are 16k front / 8.7k rear.

 

Is the ride quaility the same as stock for the most part and how much clearance do you have.

 

Ride quality is not going to be the same as stock for my height, since you limit the amount of shock travel. You will need to find the right balance of height and damping settings. Since I lowered it so much I had to tune the damping to the softer side so that the bump stops do not hit my fender over bumps, making the ride bouncier.

I'm not sure exactly how much clearance there is, but I normally don't have problems going over abnormalities in the roadways. Speed bumps are a different story. My undertray hangs really low (lower than my lip) so that gets scraped more often than anything else.

 

Do you know the part number for the ksport true type coils ?

 

I bought some Tein Basis for $600

 

Have you looked at the G37 RWD sedan post stickied in the Brakes and Suspension forum?

 

CIN-021KP is what I have. Not sure if AWD and RWD versions are different or have different part numbers.

 

AWD & RWD have different front lower shock mounts so they are indeed different part #s. Tein Basis are only made for the RWD Gs.

 

I was too lazy earlier to scroll up to check if you had RWD or AWD so I threw it in there LOL. I see now that you have AWD so that's the part number you need.
