I'm not a HUGE fan of a slammed car, but I wouldn't mind lowering my ride a bit with some springs.

Cereal, whats the fitment issue with running coupe coilovers on the vert? Spring rate in the rear?? It's not like straight coils that would sag and not support the car to the proper ride hieght if they were to weak, you can just adjust the spring perch to obtain the ride hieght desired. Unless there is a huge difference in spring rate there might not even be a noticable difference in handling. I'd be all over the coilover route if I were you....

But check this thread if you are in FL and can help out BC racing with a test vehicle.

Has anyone lowered their G37s convertible with these ? I'd like to see how it looks before i invest into them, it seams like a lot of drop.

Also found the Eibach Pro-Kit Performance Lowering G37, Convertible, Part Number: 6391.140 but no data is available for the drop. However, the G37 coupe s of the eibach pro kit lowers the car buy .8" rear and 1.2" front. If the numbers for the vert are similar i would go for that.

Interesting... They both say for the convertible but I have no idea if that's true or not. I'd probably go for the Eibachs since they're less aggressive (1-1.5" drop and the H&Rs are around 1-2" drop).

Has anyone tried these yet?

Just checked their website and the convertible isn't even listed!

Additionally you can't go by the coupe drop height as there is 400 extra lbs on the vert, so it will be a 2 inch drop all around. I have pics in my build thread in my sig.

BC Racing is working on coilovers, but no ETA on availability.

cereal, I have decided to drop my vert, thanks to diego. I am thinking either Eibach or Swift. I have emailed both and neither have anything for the vert, but gotta assume someone on here has used one or the other from the coupe. I don't want to buy until I know someone has done this, as I don't want to be stuck with the springs. Am leaning towards Swift now, but I like Eibach too.

TIA

There's someone selling a set of rear coupe springs for $50. I was thinking about getting them and the eibachs for the front but he quoted me $90 for shipping to Canada...

I think I'll just wait for a set of springs to come out for the vert.

. It will look very good, but will be a harsh ride if you are not used to it. Now the rear springs if you check the bc coilover thread the original poster said he had tried stock coupe springs, so it should be a mild drop maybe half an inch or so? I'm not sure about the front springs if he changed those to the coupe stock springs too. If anything stock coupe springs are always for sale and everyone is raving about the swift springs. It boils down to which one you may want to try first.

Lee,

I guess I have a few questions. If I do get springs, what issues could I have, other than the fender rubbing in the rear and possibly in the front? I see in your worklog about rear camber arms and spacers, but since I have a 20 offset in the front and 25 in the rear, I won't need spacers. I realize that I may be running negative camber in the rear, so that may wear the tire some, is there a fix for that, since I can't rotate my tires?

I just want an idea of what I am getting into before I proceed. Like I said, I didn't want to drop it, but didn't like the stock 2011 wheels, so I wanted something else. Now that I have the wheels, it needs to be dropped some. I guess right now am leaning on some stock coupe springs for now in the rear, but not sure what to do in the front, eibachs or stock coupe. I am hesitant to use Swift, if I have no idea how much the drop will be, since I would only like to do this once. I don't want coilovers, so that isn't an option at this point, but if the other ideas won't work above, I would consider.

TIA

I'd give the stock coupe springs a try then, but with coilovers you can have the height adjusted to your liking, so less camber wear. I'd really go with coilovers. You could also adjust damping. If you do after market springs you will hear more of the roof with the top up over bumps. That's the only vert specific issue apart from tire wear if it is slammed.

If I have to mount and dismount, I wouldn't have gone with directional tires. That is not an option at this point. I didn't think there were coilovers available for the verts. How is this different from the springs, other than they are adjustable? Also, if I do go with springs, how long should I expect the tires to last? 10K, 20K, etc.

Thanks

I made an error and just corrected it regarding he dismount/remount process. So depending on your driving habits and type of tyre it could be 6 month or more than 6 months for the camber wear to make the tire unusable if it is not directional. It was 6 months for be because i drive hard on monthly mountain runs, but this was on the stock wheels and kumho tires on the rear wheels. They were grippy but won't last long.
