    Most people don't touch any of the bushings. If it was my car, I would loosen all of them. Whether or not you choose to do that is up to you, but it probably won't matter one way or the other if you don't do anything to the rear bushing.

    I would start around 6-8C and 9-11R and adjust accordingly.

    For the LCA brackets, you can run them lower with the Vikings, you'll just have to up your rebound settings a couple clicks.

    Sounds good, thanks for the advice. With the rear hydro bushing I only ask because the Ford service manual says to tighten the 2 bolts/nuts to spec while the vehicle is still supported on a hoist. It mentions to leave only the forward LCA pivot bolt loose until the weight of the vehicle is on the tires, and then torque to spec.

    So you're saying lower hole on relo's? I'm still on the stock upper control arm, is the shaftmaster DS ok with the lca's in the lower position? Thanks a bunch!

    You CAN run in the lowest hole with the Vikings, but it will take more work and more testing to get the shock settings dialed in. Adding more anti-squat should make the car faster, assuming you have everything else set up properly.

    You would have to check with Shaftmasters regarding the LCA position/pinion angle. Dropping to the lowest hole shouldn't change the pinion angle very much, but some DS manufacturers have certain operating angle, rear u-joint/CV, and wheel base specifications that they'd like to you to use to avoid damaging the DS. For example, DSS requires a certain length between their pinion flange adapter and the DS to avoid damaging the CV joint.

    Thank you. I'm just going to order an adjustable upper and mount to ensure I have the proper DS angle. Shaftmasters specifies -2.

    Just want to say I love my BMR drag springs I installed. More BMR parts will be coming soon.

    I haven't found any issue so far but wondering if I should trim some of the bump stops in the rear after installing the BMR drag springs?

    Glad to hear you're enjoying your BMR stuff! I do recommend trimming the rear bump stops with our springs. Trimming the top tier should be all it takes.

    Improved on my 1/8th time from 6.64 at 108 to a PB of 6.44 at 110 mph also knocked .14 off my 60'. Went from 1.58 to 1.44. Need an ARB and some more fine tuning.

    Thanks for the recommendations.

    Excellent, glad to hear everything is working for you!

    Great pic, I hope you gave that Camaro a chance to check out your taillights!

    Thanks man. I gapped him so bad he needed binoculars to see the tailights. He went 7.0 to my 6.44. Fun stuff!

    For a daily driver that sees some track time what upper and lower control arms do you recommend? Wasn't sure if poly/spherical, just poly or all spherical ends is better?

    At the moment pretty much stock. I'm just starting my modifications. I'll likely be a few years before I can throw TT on it.

    Then you would be fine with poly for now.

    Lowered on BMR springs, are adjustable sway bar end links and/or a bump steer kit necessary for a street driven car?

    Here is what my tie rod angles look like in relation to the front LCA, they actually look pretty level:

    I typically don't recommend bump steer kits to people because I don't think they're really necessary with mild drop springs, like ours. It's not likely to make a big difference in how the car performs.

    Adjustable end links are also not necessary, but would allow you to adjust the bar so that it's neutral, with no preload.
