I've read some other threads about the computer reading tire speed and thinking it's slipping.
Any help would be appreciated.
Thanks
Did you ever get any help on the speedo issue and car thinking it's slipping?

I know just enough about suspension geometry to be dangerous.

It appears from poking around on this kit that this is what has been done:

- Front struts were lengthened.
- Spacers were installed on the rear springs.
- Rear dampers were lengthened somehow or the pivot points modified in some way to make them function lower in the chassis (I can't tell from the photos of the kit).

What I have not been able to establish is whether any of the following was done (and perhaps you could address this)

- Was the entire front subframe spaced down lower, thus moving the inner control arm pivots down and the steering rack down along with it? If this was not done, the lower control arms will have an excessive down-angle, which will result in an excessively high roll-center and excessive side-kick and tire-scrub on bumps.

- Was the rear lateral control arm assembly spaced down lower, so as to level out the lateral arms? If this was not done, the excessive down-angle of the lateral arms will result in a bizarre toe curve and introduce an "uncontrolled rear wheel steering" effect and plenty of bump steer.

If the above two items were done, it should drive OK in normal gentle-driving circumstances. Even if those were done, it will not handle optimally with the center of gravity raised up. There will be more body roll because you have increased the roll moment (related to C of G height) but you have not increased roll stiffness (stock -wimpy - springs and dampers). There will be more pitch because you have also increased the pitch moment (again related to C of G height) but have not increased resistance to pitch (basically, spring rates).

I also am interested in this, I'm halfway through making my own kit similar to the Daystar kit. The rear is done same 2" lift in the same mannor, simple enough, Now making the strut extension bolts and 2" spacers for the strut. Yes I'm dropping the whole front suspension on 2x3 inch blocks and then bolting through it all and adding a tack weld to each corner just to keep me asleep at nights..lol I have yet to make the steering shaft extension, but it's simple also. Just time on the lathe.

My question is, what tire size is best for this amount of lift? I am after aggressive snow tires not street crap rain tires...lol. I am doing this simply to be my winter time beater vehicle. I also do not want to sink much money into this if it's a dead end project....so any help is greatly appreciated...!
Thanks in you in advance.
