I have a 2000 TH Advance I have got some 2004 17" Verada Rims for free and will be fitting them tonight, How far should I lower the car so it looks decent but has minimal to no rubbing ?
I am currently looking on the King Springs website for what i will get how many MM should I lower it.
Is 30MM enough ?

go super low fronts and lows for the rear,.. that'll do the trick..with no rubbing :D

I went superlow on the front and low on the rear with 17s and dont have any issues (apart from the tow hook at the front scrapaing on the ground occassionally).

Youre better off getting the back compressed a little more with the king springs as the back sits pretty high on lows.

You wont have any issues with the wheels not fitting or scrubbing, you will only scrape the tow hooks when ur careless or on steep driveways..

Check with Your Insurance company mate !!

best thing you can do before modding any part of your car !
