Sporty G37 thread

I mean, if I have to get out of the house during those 3 days Plus again it's not only those 3 days. Summer tires don't like cold weather (which is why they're called summer tires :) )

But you have no problem riding on D2s lol I keeed I keed

I don't like that aspect of the first ones either, but they fit the bill on every other metric. Ideally I'd get some 19" RE30s but if I had that kind of money I wouldn't be driving a G37...................................

What are D2s? I only rep the finest of Chinese coilovers.

You lose some grip (as do all seasons, though to a lesser degree), but they aren't generally dangerously undrivable as long as the temperature doesn't go too much below freezing.  They'll be at their worst when you first start driving, but after a couple miles they'll warm up a bit and be better.  I've driven with mine down at just below freezing and they were OK.  Easy to spin the tires, so you just need to calibrate yourself and drive like it's wet/raining.  Depends on the tire, as well.  Some of the really sticky stuff (Sport Cup 2 or Rivals, or any R comp) can crack when you get down under 40F.

I've been riding top-down since mid January. You can definitely get by with summer tires here, especially a guy like Sporty with a lot of experience driving in the snowy Northeast.

You're a braver man that me. I take my ride out night-of when everyone is scared shitless to find empty parking lots for donuts. Then I'm strictly no-driving because all the locals turn into abject idiots, drive around at 5 mph no matter the situation, and abandon their cars in the middle of the road when they get stuck.

Is it really very likely that both you and the wife HAVE to leave the house separately those days? Can't one or both of you work from home every once in awhile?

When Atlanta got that awful ice storm a few years ago, I totally LOLNOPE'd out of going into the office. NBD.

+1. When the S2000 was my only car, I drove my RE-11s as low as like 7 degrees and they were fine. I wouldn't want to go speeding around a mountain road at those temps but they can handle normal driving just fine.

I have heard that low temperatures can cause pitting since the rubber gets brittle and that manufacturers can void warranties if there's evidence of low temperature driving, but I don't know if that's true or not.

I have a set of michelin X-ice Xi3s mounted on g37x coupe 18 inch wheels I use for the winter.  It crushes snow ice and cold weather.

How does it deal with ice snow?

Definitely true.

My tires' warranty paperwork says they will not cover tread damage incurred if they are used below 45F although that's pretty conservative.  Others, like the F1 Supercar, say you can still drive on them down to ~20F without risk of damage.  I know guys who have tried auto-xing with <200TW tires in temperatures near freezing and had chunks of tread tear/break out.

D2s are the same as BCs, but black and purple.

Both are made in Taiwan IIRC

I don't need those problems. Granted I drove the Z through a winter on NT555s but the little extra .15g or w/e I'd get is not worth it.

I think D2/BC and Megans and probably other brands (Feal?) share most/all parts, with the main differences coming from dynos/tuning. Hell, Sporty's own favorioute Fortune Auto might get some of its parts from that lot as well.

[12,000 RPM]

A lot of it just comes down to the brand. BC, Megan... they just don't seem serious and I've read a lot more problems from them than others. D2 actually seems OK. Fortune Auto seems to have a much better grasp of what matters for good coilovers and they have good customer service. I'm leaning more towards Powertrix

Nothing good ever comes from chinese shocks.  Just get some bilstein's and get it over with

Even better

Decent

I haven't had any problems with my BCs and they've seen track and autocross use.

The STs on my Civic were made in Germany by KW, and blew in less than a year on pretty smooth roads

[68_427]

My BCs have lasted over 20K miles on shit Rochester roads

I know BCs are used in formula drift as well.

Yeah, and FD cars are put through far more abuse than pretty much any other form of street motorsports, so if they can handle that environment I'm sure they'll be just fine on Sporty's G.

FD cars do not deal with rough roads, the need for ride quality, longevity, or ability to handle road salts and dirt...  There is nothing applicable between FD and the street for suspensions

[Tave]

Don't they modify the front ends too for the 180-degree lock?

OK, in that case mine are still going strong after 3 years,  25k miles,  5 track days, and numerous autocross miles.  If they last on my car I'm sure they'll be fine durability wise for Sporty.  I don't know about his comfort or valving requirements, but they're not junk just waiting to fail either.

PSS10s are within what I can stomach price wise.... Tire Rack has a sale.

Not quite to that point I don't think, but yes.

Buy PSS10s, set to full or almost full soft, enjoy life and never think about them again
