Yeah, that's kind of a problem. The camber is supposed to be between 0 and +30'.
There are a couple of ways to fix that. Some have slotted the bottom A-arm holes and made sets of shims that fit neatly in the A-arm with holes that change the camber. Yeah, that sounds like a lot of work to me and fraught with the possibility for errors requiring you to do a lot of extra work! But then if you have the time and want the challenge...
On the other hand, you can buy adjustable upper A-arms. I have a set I got from Richard at Banks (now Lotus Supplies at
https://www.lotus-supplies.com/parts/). If you go the route, make sure you get bushings with it. That will require you to take the upper suspension pivot pin out and all that entails. The upper ball joint screws in and out to adjust the camber. IIRC, Richard said a turn equates to 3/8° so you should be able to get a reasonable camber value that way. I don't know that Lotus Supplies is the only place to get such a thing so you might try some other places if the price is scary.
