19" tires for a 08 g35xs sedan...
#18
Bat, many people who don't understand tire sizes thinking simply a lower aspect ration (the middle number - 40 or 45) mean a shorter side wall. While that's true it is actually not that simple. It's an aspect ratio, a percentage of the tires width. For example: 225 (mm of width) 45 (% of the tires width - 225 divided by 45) 19 (inches of the tires inner diameter). Knowing this you can do some math. You'll see a 225/45/19 has approximated the same side wall height as a 245/40/19, but the 245 is wider. Your car may ride slightly different with 245/40/19 as opposed to the narrower tire, the side will not actually shorter.
I also would like to strongly discourage you from using a tire that has a vastly different outside diameter than your stock tires... doing so would effectively change the final gearing of the car, as well as throw the speedometer & odometer off, and can also effect the ABS system. This becomes very apparent when you put oversized tires (that are like 2 or 3 or more inches larger than stock on a truck, but can also be noticeable with smaller changes. If you are within a 1/4" - 1/2" of your stock diameter, then you should be fine, as the overall diameter of a tire can change this much over it's life just from tire wear alone.
Let me know if you need any other help with tire sizing, etc... I sold tires for Michelin in a previous life, so I've been through all of this before.

This is simply a gorgeous picture, AesonVirus... Beautiful car you got there... and the GT-R isn't too bad either.
Now you just need some Impul's or Eibach's and you'll be all set. I'm still trying to decide which springs to go with on my car.

I dont think he understands that the 2 sizes have the EXACT same outer diameter even though one is a 45 series and the other is a 40 series.

I'm totally sold on the Impuls. I have been since Ddubb did his G last year. I'm still working on securing the cash for the Springs and I'm also shopping around for a local shop to do the install.
It's only a matter of time!
The GT-R belongs to a friend of mine. In these pics, his car was something like 5 months old and he was still on the same tank of gas. Later in the evening, another GT-R pulled in and he had something like 60K on his already.. it was his daily driver... winter and all!
Must be nice.

I probably should have been as concise as you, but then again, I like to talk a lot. LOL

Thanks dude... My car was one of the first at a local meet last fall and some guy walked by and snapped that pic. I then found it posted on a Mazda forum of all places. That meet ended up being one of the best anyone can remember in recent years. Awesome time!

Can I ask you what made you choose the Impul's over the Eibach's. I'm just not sure I can justify the price difference for the Impuls... although, I'm trying very hard too. Also, why not install the springs yourself? It's actually a VERY easy install, especially if you have a spring compressor tool.
Oh, and tell your buddy, I love his GT-R... That's probably my next car... just like his... an ivory pearl GT-R!
Sorry, Bat, I didn't mean to hijack your thread....

Even at stock height, I'm touching frozen crap in the middle of the road during the winter months. My drop has to be subtle to rid me of unnecessary wheel gap but the car needs to remain practical as my daily driver.
I also like the idea of it being a minor drop, which will save a little extra life in the shocks as well.
Installing them myself... I considered it until I read some horror stories about the front shafts popping out in the X. They're a nightmare to get back in. I have two little ones at home and the wife always books my weekends solid. Any project I take on has to be small. I'll have 2 hours allowanced to me (tops) if I decide to do these myself.
It's easier to hit a shop and drop $150.
Besides, I love watching other people work.

2GoRNot2G - Get the Eibachs. You live in SoCal. No need to worry about clearance for snow. The Eibach drop looks better and the springs are 1/2 the price of the Impuls. I've been running Eibachs for a while and the ride is fine. The car doesn't bottom out on the bumpstops, handling is good, and it feels like virtually no compromise. IMO, the drop w/ the Impuls is too subtle.
AesonVirus - I hear what you're saying about doing work yourself. I used to do all my own suspension work. Just before I got my G35, I unlowered my TSX when I was trading it in. After I was done, I felt all beat up and sore, not to mention I had to take time off during a workday so the kids wouldn't be coming by asking me a million questions, etc. After that I decided my days of wrenching on the car (w/ the exception of super easy stuff like oil changes) was done. So, I paid $150 to have someone lower and align my G35.

Of course, if you don't have the time or don't feel comfortable doing the work, then by all means have it done by a Pro... It never hurts to pay to have something done for you, if it means its gonna be done right.
Good luck and let me know how you like the Impuls!

Hehe... I know what you mean, but I never trust anyone else to do it right, so I always do the work myself. I'm in the same boat as you and have 2 separate companies that I run, so my time is very slim, but I can usually find a couple of hours to work on my car...You should be able to knock the springs off in an hour and a half, two tops. I wouldn't worry about the front half-shafts poppoing out of the spline, just be careful when you are doing it and maybe even use a coat hanger to keep the front spindle from dropping too low when you have the shock removed.
Of course, if you don't have the time or don't feel comfortable doing the work, then by all means have it done by a Pro... It never hurts to pay to have something done for you, if it means its gonna be done right.

Hey man... Thanks so much for the nice review on the Eibachs. That sounds like exactly what I'm looking for. I was just affraid that they would be too stiff. I don't think I can justify the price difference for the Impuls.. they will end up costing me over $400 more than the Eibachs even if I do have to buy a rear camber kit, that will only run me $150 - $200, so I'm still quite a bit cheaper with the Eibachs.

But, yes, I would recommend the Pro-kit (unless you are going to go bananas like kulg35 and install electronic adjustable coilovers...bastard. I kid, kid. but i'm green with envy)
