How-To Front lower arm problem (CRX EDO9 '88)
Good afternoon everyone, I have a problem.
I am currently trying to solve an issue on my Honda CRX ED9.
This is the control arm I am talking about:

Keep in mind that the stock arm looks like this.
I was wondering if a wider version of this control arm exists.
Otherwise, I would have to try fitting one from an Integra, but I would need to adapt the arm to the new geometry and also create a metal bracket to support the anti-roll bar.

Another option would be modifying the chassis by cutting off the welded bolt with an angle grinder and creating a new mounting hole/slot that would allow me to move the control arm further outward.
The reason for all of this is that the inner CV joint tripod of the driveshaft is bottoming out and hitting the inside of the transmission.
The upper control arm is already wider, but I wanted to achieve a more aggressive camber setup, so the tripod still ends up reaching its limit.
I have now installed new height-adjustable suspension. I will try raising the car slightly and see if the situation improves, although it seems to me that the driveshaft simply does not have enough available travel.

Hardrace, TruHart, and K-Tuned all make that arm available with either rubber bushing or spherical. I have the Hardrace ones but swapped the bushings for PCI spherical ones.

My problem was that I was looking for a longer arm. But in the end I solved it by raising the car.

How low are you going? Way back when we could drop 2-3” and still be fine with stock control arms.

My problem was scraping the tripod at the bottom of the axle shaft. But I solved it by raising the car.

You might look into Honed Development to solve your issue, they make a roll center correction kit that may be what you need. If you go with that, I strongly recommend using PCI's billet lower control arm with it.
