i am going to install,my modified k-member soon,i wondering if i need to install washers or shims,between the frame and k-member.

 

It would all depend on if you have any clearance issues. I would think that sub-frame shimming MAY induce bump-steer. I would suggest that you get the car together & "see what you got". You can always add shims if needed. Seems to me me that shimming the engine & transmission would be the best way to go.

 

I shimed my last one down 3/8ths of an inch and I do get a bit of bump-steer. It's not what I would call "bad" but it is noticable.

good info MRM331, I buy Type-R tie rod... hope that help... i down my rack about 1/4 inch.

 

That's my ultimate plan when I get around to it. Another option (that I've heard of) is RX-7 lowered tierod ends from Megan racing. I have not seen them in person but they look pretty slick.

Ya i look that it, but the angle are not the same, think some drift guy use it.... anyway in my case i have 1/2 inch of clearance so i can raise it again.

If you try it, let me know how it's work...
