I have. Going to cut 3 inches and weld it back together ...mine hits the wheel well with out being compressed

 

impossible to do it without having to re manufacture a new piece.

 

I'm pretty sure you can cut and weld

 

simply cutting and welding wouldnt allow the control arm to move at that angle to meet the top of said piece you would be cutting. i would think you would have to relocate where the control arm meets the body in order to keep the proper functionality of the suspension. I would like to say the better thing to do would be reform/remake the inner fender well so there would be more clearance, i.e. cut a hole, weld a new piece in.

 

looking closer at the piece, it looks like it is also cast. Dont people run into problems with welding cast metal?

 

Looks to me like you could get away with cutting out a small portion which may be enough to gain some clearance...Even a small amount cut out would yield a good amount of additional clearance. You can weld cast all day, as long as you have the heat up...and the best thing to do would be to cut it and then with the piece off the vehicle, make the joint between the two "V" shaped and fill it with weld. A few passes would most likely do. If they can weld two pieces of 1" thick plate together, you can most likely weld this skinny piece together.

 

You're a madman if you cut and weld that piece. Seriously your life and others on the road are in jeopardy. It would be a miracle if that didn't break within the first few months of driving.

IS300s can get plenty low enough without pulling hack jobs on vital suspension parts. Keep one finger gap and enjoy a pleasant ride and more aggressive handling characteristics over stock.

 

It is cast steel and I would not cut/weld the steering knuckle. I know for cast iron you would need a special NI-ROD for welding, but not sure of cast steel. I would not tamper with that, that's just my opinion. If you would then I would do as dakinISbatman said and weld in two plates across the cut as a filler weld won't be able to handle the stresses. Don't do it!

 

I agree with five hour and Jason. The structual integrity will/would be comprimised (sp). I saw that in person after a supposed "fix".

 

if you cut that and lower it it will put it closer to wheel and will more then likely hit tire.

ok so 3 inches is alil much but 1 inch is fine stay tuned because this will happen..and before anybody gets all crazy and claims im going to kill someone RELAX my is300 is a track ONLY car and will never see the highway/city

 

Welding cast steel is ok, as long as you use the correct filler rod, and use enough heat. I have welded many sets of 240sx spindles to get more angle. There are 2 blog posts that show how I "v" the joint before welding.

this is retarded. the car gets plenty low

 

The IS300 cannot get that low at all, well not without being functional. The front suspension is is the limiting factor, since it will always bottom out.

If you want to cut something, just cut the wheel well to allow it to go up into it, prob be alot safer.

This does not help with the suspension geometry. Shortening this piece will allow for the upper A arm to come closer to its original position.

until mike gets done with the A arms i cant cut anything since i need to see how much room ill need for camber. everyones cars are all set up diffrently for different reasons. Ill need to be as low as i can, while still have full suspension travel. With only about an inch of room that could make a track day go bad.

 

Exactly, I want to be low, but still be able to drive my car. If it is bottoming out every where, it becomes no fun to drive. And if the car is 4x4 status, it is pretty ugly.
