    But it looks like you hit something?
    There are quite a few options other than DPI.

    All the lower control arms are an inferior design as far as I am concerned, some one needs to make an A-arm style LCA.
    You can get braces from DeloreanGo or DPI though that triangulate the LCAs.

    Listed by cost:

    Factory Boxed and re-enforced - DeloreanGo or Clint Wolff (Clint does great work)
    Byrne Heninger heavy duty steel - NLA, may find some used?
    Stainless - DPI
    Billet Aluminum - DMCMW

    I got the boxed in LCAs, stainless and triangulated LCA brackets, PU bushings and the ventilated front brake rotors - all from DMCEU. A plug also for QA1 where I got the adjustable dampers and adjustable ride height springs.

    Agree about the poor design and need for A-arm style.

    Looks like DeLoreanGo also sells a billet aluminum style. At $1300 I'm not sure where they land price wise though; probably near the top. (anodized black instead of raw): https://www.deloreango.com/us/alumin...trol-arms.html
    I think DeLoreanAutoParts also sells boxed style ones.

    The whole front end suspension was an engineering compromise using Lotus's designs of the period. While it has it's drawbacks, it is an efficient and functional design. It can be improved but is it worth it? Most owners are not racing competitively and the car is not a daily driver so it isn't abused and is used infrequently. Hard to justify spending a lot on it.

    The boxed LCAs and the side support brackets perform different functions. Boxing or reinforcing the LCAs prevents catastrophic failure of the LCA. The side brackets minimize/limit the amount that the arm moves fore/aft (changing the toe and alignment) under braking, acceleration, turning, etc. You wont notice much of a handling difference when boxing the LCAs (but you'll sleep better at night); you'll definitely notice a handling difference with the side brackets.

    I'm running Byrne's LCA's on 5052 and DeLorean EU's LCAs on 4194. I find them to be very comparable in function, strength and appearance. Both weighed in at about 8 LBS each, which is twice the weight of the stock LCAs. All of Byrne's products are NLA; however, to the best of my knowledge the EU LCA's are still available. I would recommend them highly.
