Alright guys. Dilemmas dilemmas!

Well, I'm getting 20 inches soon.. I know the car will sit high with that 20's...

I'm going to see how much 20 inch will raise my car(I have journey's 17).

From what I can gather H&R gives you the pretty conservative drop(how

much drop is it?).

I really really do not want to scrape my car. So do you think my car will sit

almost the same height with 20 inches rims + H&R springs compare to stock spring with 17 inches?? Any thoughts?

I would get a coilover in a heartbeat if tein basic was available... any

projected date on these puppies?

Hope this help.

 

it wont raise the car at all
it all depends on tire size
you'll be at stock height with 20s

and H&R has a pretty nice big drop
eibach is a just a bit higher than H&R

 

hmmmph

usually how does a dropped G on lets say Eibach on speed bumps and stuff?

My friend's lowered scion Xa scraped everytime we went over a bump.....!

even at idle or low speed.

 

well H&R lowers the front much lower than eibach does so you might scrape with H&R but eibach lowers the front and rear a fair amount, just enough not to scrape.
obviously if u drive fast you'll scrape, but once you drop your car. you are goin to slow down twice as much than you used to.
it becomes a habit.
you'll do it without even noticing lol

 

this is an eibach drop
this is B L U E S L A T E S car

 

You'll be more worried about running your lip up the parking blocks than speed bumps on Eibachs. As G25Robby says ... H&R will lower your car even more.

 

that looks so beautiful! hahah but... I have a oem lip kit..... I think I will unequivocally scrape everywhere! lol

 

well if u got a lip and if you wanna drop your car, i hope you know how to keep your distance from those parking blocks lol
and also watch out for big dips, people usually go over them diagonally so they wont scarpe

 

Well, the diameter of the oem 225/55/17 tires are 25in. The 245/35/20 tires has a diameter of 25.8in, and the 275/30/20 rear tires has a diamater 26.5in. With these tire setups, the front is rased 0.4in from stock, and the rear is raised 0.75in from stock. This is the case I believe, correct?

If so Eibach drop is about 1.4 front, 1.3 rear, therefore overall 1inch drop in the front with that setup, and .7inch drop in the rear? Is this calculation off? lol...
Since the diameter of tire is changing how that would effect my meter? Will it show lower speed thatn what I'm actually doing?

I know I have too many questions lol

 

With bigger wheel/tire diameters...
Yes, it will be off, ever so slightly, maybe a couple clicks or so, showing slower speed on the speedo than reality. If you don't have AWD (G35X), this is OK.

Your VDC (traction control) will kick in slightly later, but nothing that will make a noticeable difference.

And obviously, if your tire/wheel diameter is bigger, it will obviously "lift the car" by the difference in radius.

If your roads are bumpy where you live, stick to eibach as H&R's drop the front more (lower the drop, the less movement in suspension=bumpier)

 

yeah eibach sounds like the best thing,

is rear camber and alignment enough for longevity and even tire wear?

hmmmph I always wondered that.

 

I put one on (rear camber kit) as it is too far off without it (based on someone's post here with the alignment report)

Do it right the first time, put on a camber kit (rear) and you'll be golden for tire wear and longevity....unless you are purposely wanting to run negative camber which doesn't seem to be the case.

 

Your calculation is wrong. The overall diameter of a 225/55/17 tire is: 225 mm width x .55 aspect ratio x 2 / 25.4 (converting mm to inches) + 17" = 26.74"

245/35/20 = 26.75" which is virtually identical to stock.

275/30/20 = 26.5" which is just a tad under stock.

Bottom line = if you go with 245/35/20 and 275/30/20, your ride height will be virtually identical to stock.

Now, this is just based purely on math. In real life, the tire diameters can vary slightly from brand to brand. If you want to see exact diameters, just go to tirerack and look up the specs of the actual tires you're interested in. They will list the specific diameter for each size. Still, the deviations between various brands of the same size are really close - like within 0.1"

Just curious - how are you calculating the diameter of your tires? How did you arrive at 25" for 225/55/17 and 25.8" for 245/35/20?

 

Just keep in mind that alot of these pictures are with the car EMPTY. Folks dont seem to think about the time you have 3 or 4 adults in the car and then the ride is much lower. Or if you are performance driving, under braking , etc. The car needs a little room to perform. I've certainly scraped up the splash guards a few times when the road is bumpy and Im braking hard. Just dont go too low and you'll be fine.

Depends on your type of Driving I guess.
