What size tires are you going to use?

I really don't think they will fit in the front... 35 offset will probably cause them to rub on turns.

Overall diamter is smaller by 14mm, side will stick out 10mm

Future / Current
Beyern Type Mesh Silver / OEM Style #114
Hankook K104s / Dunlop Sport 01
245/40-19 19x8.5 40ET front / 235/50-18 18x8 46ET
255/40-19 19x9.5 45ET rear / 255/45-18 18x9 51ET
H&R springs / oem sport springs
Balance, alignment, labor
total = $2500 (I think its a good deal if that includes tax)

Edit: eurorev quoted me $2000 for 20" + tire + mount and bal. They told me they have put 21"s on a X3 before, forgot the brand of the wheel. I guess I'm going w/ 20s :rofl:

that's my concern... during a full turn what is going to happen? rub? hit suspension components?

go for it but if you're going mail order ask what the return policy is...


btw, based upon my personal experience, Eibach springs are going to be "softer" than H&R; for everyday use, Eibach might be a better choice IMO.

also, you may want to look for different tires... i was looking at hankook but after reading reviews (tirerack.com and other sites).... "you get what you pay for."

10mm = 0.4 in. I don't think it should be a problem. Eurorev is a local shop by my house and they said they will guarentee fitment. Too bad the 20s are not instock. Gotta wait 4-6 weeks. :(

Thanks for the tip on the springs. I do more research on them. As for tires, I'll probably go w/ Toyos.

Ok, guy quoted wrong tires. 235/45-19 will be perfect. Width will be the same. Overall diameter will be 2mm bigger which is nothing. Now the problem w/ the 20s is that there is no perfect fit for the front. I would have to go w/ 235/35-20 which will cause my overall diameter to be 2.2" smaller. Width will be the same.

hmmm looked at Eibach site today; they are being "developed" by Eibach... i thought they were already available... :dunno:

They are avaliable, i've seen it. BTW no go on the 20s cause there are no correct fit tires for the front wheels. The tires are either too tall or too short which would cause traction control problems because the front wheels will be spinning at a different speed than the rear.

If I make sure the tire diameter is the same on both front and rear (spining at same speed), technically it shouldn't cause any computer problems?

THIS IS WITH 275/40/20 (20X8.5 5-120/114 18C) it fits fine no rubbing .i have more pictures available .

Just one thought about the eibach springs...

I would hesitate to lower the car without matching struts. What ends-up happening is that the OE shocks have x inches of travel (let's say 8 for argument). If you lower the car 2" with springs using the OE shocks, you lose a 2" of travel. This will hurt the ride substantially and will cause the car to be jumpy in turns. Moreover I think you increase the roll-over risk because the shocks will always be partially compressed. Thus any time you put the shocks into rebound they may tend to rebound more abruptly thereby causing tipping. Add grippier tires to the mix and I think it is a bad recipe.

If you are going to do springs then do shocks too. The only maunfacturer I found who does both is AC Schnitzer, but their setup is hella expensive.
