Good idea with lca mod but id be worried about the stress and liads on the welds at the ends of the lcas.
Cheers mate any input is appreciated I have had this in mind. The lad i got to weld them up for me has done loads of lcas for Vic drift club and not had a problem as yet. I will be keeping a very close eye on them non the less.
The problem you will have with s13 knuckles is the steering arm is too high, relative to the steering box. This results in about 15mm of bumps steer. Probable the worst thing you can have in suspension.
The options you have to fix are
Bend the steering arm down to the right height (this has to be done right and crack tested afterwards)
Lower the inner control arm pivot (not recommended as this lowers roll center)
Raise steering box or install raised rack and pinion system.
Thanks lampy i had not even taken this into consideration and the last thing i want is exesive bump steer . I had a bit of a look with the knuckle and coilover in and the steering arm looked to be on a slight angle up but not much. How much of an angle is to much ? I would love to go rack and pinion at some point down the track but just not yet. bending the steering arm down and crack tested might be my best option.

Do you want the car to be legal?
The difficulty is the component you want to modify is it is considered a suspension component. Suspension components generally are not allowed to be modified at all. This includes welding/bending/cutting/ etc.
The reason for this is the impact/shock loading on the component will require analysis and the OEM have already completed this and strengthened this area up if it was prone to failure. By you cutting and welding in a new section, you are changing the specification and strength and in turn affecting the performance under load. This will make it prone to failure.
What is legal these days
Don't get me wrong I want it to be safe. I have looked into other LCAs and still looking just had no luck.
