While getting an alignment, we noticed there is some damage to the arm where the toe link connect. Because there is a small chunk of the arm missing, I am only allowed certain adjustment and unable to align the car the way I want. I assume the only fix is to replace the whole arm? Are there other options?

I would replace that.

I'm sure you could find someone to weld and machine it, but it wouldn't make sense due to the price I usually see them on eBay for.

Edit: that's a big chunk, you will need another one

Another option would be Tarret arms, they are designed to adjust from the arm, not the eccentric

Time for a replacement arm. If you get a used one, make certain that its not bent.

That's not an arm that is broken it is the side mount, KT arm adjustment

replace the sidemount

It seems the part that is broken would not account for the lack of the range of adjustment. Is somthing else bent. Several web sites have a diagnostic sequence to help you ID the additional; bent components.

Yeah its the wall that pushes the K toe out when turning the eccentric bolt.

I'm curious how it would have broke? A lateral hit to wheel could have done that or ???

I have never used Terett, but I'm pretty sure they bypass that form of adjustment.

Nothing else is bent but I have no idea how the PO broke this piece as well. Looking at the Tarett rods but came across all the links that Rennline offers. What's the difference?

Those are mono-ball arms, great for a track car not what you want on a street car

you need one of the side members, labled subframe here

993.331.051.01 /L
993.331.052.01 /R

or the equivalent RS parts if you do both sides
993.331.051.80 /L
993.331.052.80 /R

Bill, thanks for the info...I looked on Pelican and its over $1100 per side! I'll probably just stick to the Tarett links to get more adjustment for now

Bill Verburg

Do what you want, but changing the arm does not cure the issue.

Try Sunset or Hennesy or a salvage yard

What are benefits of the RS arm?

daedton is parting a car, I'd start there.

There is one on eBay for about $550 or make an offer, and another for $350.

That sidemember needs to be replaced, no if's and's or but's.

I personally wouldn't drive it until it was fixed. As some stage this has taken quite a lateral hit high on the wheel (Above the hub) I would guess that how ever that occured a wheel would have had to be replaced when that happened.

One thing to mention if you go to Rennline or Tarrett links is the use of a centering washer that eliminates the adjustment slot. Square washer with a hole constraining the adjustment to take place in the links rod ends. With whats left of the lug the washer will work with the current casting.

Since the lug and bolt eccentric do not take the full load, much taken by the clamping force of the bolt with the eccentric holding static position. But I have had mine move so the bolt clamping is only so good and depending on where the cam position is it can "unroll". It is something that needs to be replaced or if you can't find a reasonable one welded up. I would have no issue with it being welded were it mine since I would be welding it. The casting looks clean, not oil soaked, so it will repair fine. Key is if you go that route it needs to be someone that can competently weld cast aluminum.
