Default Lowering Guhru...please advise!!

Ok..I used to sit really high and like it much better now.....BUT!

The front tire to fender gap is about 1/2 inch larger than rear. Had new Z06 springs and Bilstins done along with long rear bolts and cut some of front bushings.

Suposedly the fronts are adjusted all the way down. Have had the rears adjusted up once already to try to compensate. I like the rear where it is (2 fingers). Is there anything else to do with the front? Will raising the back MORE ever get the front to come down???

I just had this done 4 days ago with about 250 miles driven. Will the front settle??..am it being too impatient? I know I need an alignment (pretty new tires) but obviously need to get all the lowering adjustment and settle in time out of the way. How long should I wait.

Please advise.....

(Note: will update sig pictures when lowering done)

3 choices...

1. cut more of the front bushing. (2/3)
2. raise the rear
3. wait a month & see how much it will settle. (it will settle)

2/3 cut front bushing & longer rear bolt.

Mine sits much lower than yours in the rear! (I really need to uplaod some pics of the new stance)...I don't want to raise the back that much to lower the front.

I will check ... maybe only 1/3 bushing was cut.

Thanks....I didn't realize that waiting a month may be necessary. I hope my tires don't wear......I drive about 500 miles per week!!!!!

The rear is as low as I could go with the 335s on 11.5 wheel.

Mac,
If you are driving 500 miles per week then don't wait a month. One week should be plenty at that rate.
Do you carry anything heavy in the rear of the car?
How much fuel was in the tank when you made the measurement?
The difference in a full tank and an empty one can be 3/16". So figure that in.
If it were me (I have lowered several cars) I would raise the rear about 4 threads on each side. Then get the car aligned soon. Did I say soon?
If you have to make some final height adjustments after the alignment they will be small and will not affect the alignment enough to worry.
The front will probably settle a little more.
Dave

Thanks for the advise. We have raised the rear two times by 4 threads (three days after install). I hope there is more bolt thread left. I did notice that the rear droped about what you said (3/16) when I filled her up today. I am going to make any more adjustments with 1/2 tank full.

I appreciate your experience....did you cut front bushings and by how much? There is nothing more to do on the front in your opinion??

Thanks

pull the front adjuster bolt completly out of the front springs and the car will sit as low as you can go without coil overs.

Have you done this?

I'm no mechanic but this seems rather drastic!

However, if it is not detrimental to the proper handling of the car I would try it !!!

Ok...I raised my rear up to 26.75 from 26.5 at last adjustment. So I can easily go back down.

In the front....can I get to 26 without removing the adjuster bolt. And I assume if you remove it then you are stuck at whatever ride hieght it comes out to be and thats it.

You say no problems. Do you track or drive canyons hard? Any funny noises?

Thanks

Have you measured the true front and rear rake by measuring the fram to the ground both front and rear?

Yeah, no adjustment after removing the front bolts. I had no noise, but I
can't say I drove it real hard before switching to coilovers.

I actually tried one day but couldn't figure out where or how to measure. Obviously you have to get down on your belly...

Tell me how and I will do it so I know the real rake.

But I still want the front tire/fender gap to be smaller/equal in the front than the rear!!!!!!!!!!

no front adj bolts left here either.. I just drove around the block and it was as settled as it was ever going to get though. Longer bolts were installed on back.. I'm actually going to raise the back up just a tiny bit as there's no tire to fender gap at all right now and doesn't look right. The front stance is perfect IMO though. Definitely going to get the alignment. After a year or so the affected camber has trashed the inside edges of my front tires.

Mac,
I did cut some of the front bushings on my car. I think it lowered the front only about 1/4" more.
I know others have removed the front adjusters but I would not do it to my car. That's just me.
It sounds like the rear bolts that were installed were too long for this application. Generally you do not need longer bolts in the rear unless you cut the front bushings.
You have changed the rake on the car and it is too low in the rear as compared to the front. Another 4 threads up will help.
Are you doing the lowering or is a shop doing it?
The reason I ask is that the rear is very easy to raise. Just takes 2 wrenches and you don't have to jack the car up.
Dave

I cut 2/3rd off front bushings in front & cut the top ring off the top bushing in the rear & went all the way down on the stock bolts, The fender wells are 26" in front & 27" in the rear. Car is 1/4th " higher in the rear. Ground clearance is 3&1/2 in front behind front wheel & 3& 3/4 in front of rear wheel. Air dam is aprox. 2&1/2 from ground Looks great ! But I have to be very careful on speed bumps & driveways!
