I am going to be purchasing springs very soon. I also plan on flushing the stock wheels up with some (10mm?) spacers soon after.

I've seen it has been done with TRD springs pretty easily, but I wanted to go with the Eibach Sportline springs for a bit more low (1.3" F 1.7" R).

Two questions:

1. Does anyone think I'll have issues with rubbing when I hit bumps with the Sportlines?

2. How about a staggered look with spacers in only the rear? I'm sure it's not ideal for performance, especially with a FWD car, but I'm just thinking out loud...

 

Im not sure about rubbing, you may have to roll your fenders a little. 10mm isnt too terribly bad, but id take a tape measure and go from the sidewall of your tire and see how far out 10mm will put you...I plan on doing this shortly as well.. Im interested to see what the rest of SL has to say. Im dropping mine 2"F and 2"R on Megan springs and tokico blues...so i will watch this post for sure!

 

You shouldn't have any issues with rubbing. Wellesley is running 9.5" +35 et, which means his are over 1" closer to the fender than stock. 10mm spacers are only about 2/3" farther out than stock.

But I'm very interested to see how it all turns out. I'm planning to switch to Sportlines in a few months.

 

That's what I want to hear!

Now if I only knew how you came up with those conversions. I have no idea how offsets work with regards to wheels. Is that measured in millimeters? What is the width/offset of the factory wheels?

Also, you say 10mm spacers are about 2/3" farther out that stock. When I look at my measuring tape, 10mm is less than 1/2". Is there something else that comes into play?

And you didn't type it in pirate

 

The stock wheels are 18x7.5 et 35, so a 18x9.5 et 35 will stick out exactly 1 inch more than stock.

There are many wheel offset calculators online, but basically if you keep the same offset and make the wheel wider, just divide the width increase by two and that is how much further it will stick out. If you keep the same width and lower the offset, then however much the offset is lowered is how much more it will stick out.

Wheel offset is in millimeters, so the 10mm spacers will basically turn your wheels into et 25 vice et 35.

Hope that helped.

That absolutely helps. Thanks!

And now that I think about it, dividing the wheel width increase in half makes sense. Half of the increase will go towards the inside of the car and half the increase will go towards the outside of the car.

So, lower offset numbers mean the wheel comes further towards the outside of the car?

 

First, you are correct (and I am wrong), 10mm is less than 1/2". I read my conversion chart wrong.

Second, you are correct about how widths and offsets work. Same offset on a larger wheel, half goes inside, half goes outside.

Third, I though I read somewhere the stock wheels have a +38 offset, not a +35. And while 3mm is very minor, that's how I came up with Ted's wheels being over 1" farther out than stock.

Last, and this is really just geewiz information at this point. Offsets can actually go into the negative, but that's more of a truck thing.

 

Now I'm just about completely caught up. Thanks a lot guys.

I wasn't sure if this would go into the suspension section or the wheel section...it looks like the conversation shifted in a manner that should put this in the wheel section.

Well to get back to suspensions, my SportLines shipped today and will be arriving in a couple days. Unfortunately, I work this weekend so I have to wait until next weekend for the install.
