I thought that getting larger diameter wheels would lessen the wheel gap, no? Isn't going from 17's to 18's, assuming tires being constant size, a 1/2" up from the ground, and a 1/2" decrease in wheel gap?

 

For example

I had stock 17 on 225/45 meaning sidewall is 225*0.45=101.25mm
Total diameter would be 101.25*2 + (17*25.4) = 634.3mm

My new 18 is on 225/40 meaning sidewall is 225*40=90mm
Total diameter would be 90*x + (18*25.4) = 637.2mm

Difference is only 2.9mm which means my wheel gap shrunk by like 1.5mm which is nothing

If I got 225/45 on my 18 then yes would be half inch increase all around, but there's also problem of rubbing
Usually people always go lower profile than stock, but like 225/40 is a pretty common size on 18x9

 

Ahh, okay. That makes much more sense. Thanks for the explanation!

 

Try to stay away from anything with a 35 in it lol they get expensive

Are you dropped on F-sports? Are those 19's?

 

Yes and Yes

 

Just got done with putting the H&R on mine. Its a perfect drop for me, not too much at all, and i like the new feel. Just went with springs, might go for struts next. But for now, really impressed with the feel.

 

H&R ftw not a HUGE difference in drop (in numbers) compared to like FSport or HTech but makes a big difference in the looks I think

 

Here you go.. some facts taken directly from each source:

2IS F-Sport springs:



Eibach Pro Kit:




F-Sport drop level = Front - .98" / Rear - .75"

Eibach drop level = Front - 1" / Rear - .8"


As you can see.. the difference here is literally down to hundredths of a decimal. How can anyone say that Eibach's make that much of a difference when compared to genuine Lexus F-Sport springs?


Give me F-Sport.. all.. day.. long.

 

Fsport springs are made by eibach, they just have the Fsport logo slapped on.

 

..which makes this debate get even funnier by the minute..


..and in that case, there's no question which I would install. Less aftermarket/more OEM = better resale value and appeal.

If it's not made by or for Lexus/Toyota, it doesn't go on my vehicle. Just me.

 

quite surprised with the drop, thought it wouldn't drop this low

 

First of all, Eibach makes the lower springs for Lexus and Lexus calls it F Sport.

Second of all, there are 2 Eibach Pro Kit for the IS:

Look up RSXiMUS recent post for his car pictures, he just had the F-sport springs put in, the car looks low and really nice. If I didn't have a baby coming and 5 speedbumps and 2 dips close to my house, I would consider the F-port springs and shocks combo for simplicity.
