BlkGt3 Posted March 1, 2013 Share Posted March 1, 2013 OK since the M3 is RIP at Sebring I needed a replacement TT car so going Wrong Wheel Drive for a change. Need to clarify one of the rules, yes I could email Greg but what fun is that, 10) Non-BTM rear control arms on FWD vehicles (for stiffness and wheel alignment only, no change in suspension mount or pick-up points from stock) +1 (if both front and rear use E.9) What exactly does Non-BTM mean in this instance. Does it allow aftermarket rear control arms for 1 point? Is this a FWD goodie over 9) below which is 4 points. VS 9) Replace or modify control arms (other than plates, shims, slots, or eccentric bolts/bushings for simple camber/caster adjustment only) or RWD/AWD rear trailing arms (may have spherical/metallic joint for the connection to the spindle/knuckle) +4 Peter Quote Link to comment Share on other sites More sharing options...
ILIKETODRIVE Posted March 1, 2013 Share Posted March 1, 2013 Congrats on joining the Dark Side! It all depends on the platform. For instance: On older Honda/Acura cars (88-00 Civic, 90-01 Integra) the rear lower control arm (RLCA) is basically just a mounting point for the rear shock and acts as a bridge between the rear of the body and the rear trailing arm. The rear upper control arm is where all the magic happens for camber adjustment. SO, if you have an older Honda/Acura in mind, don't bother wasting a point on aftermarket rear lower control arms UNLESS they come with sweet spherical bearings AND you plan on doing more spherical bearings throughout the suspension, Otherwise, just get brand new OEM replacement bushings for the arm and press out old/press in new.

Ok still learning the differences from the M. You referenced the lower control arm but 10) does not distinguish between the upper or lower arm.

ILIKETODRIVE Posted March 1, 2013 Share Posted March 1, 2013 Correct. In the case of an older Honda/Acura, you would only want/need to replace the rear upper control arms to allow camber adjustment. Replacing the rear lower control arms by themselves would be a waste. Replacing both upper and lower rear control arms would be fine but you would only gain any real benefit if the rear lower control arms had spherical bearings in them AND you were already taking points for having spherical bearings throughout the suspension. Other than that, replacing the rear lower control arms is a waste of money. AND if you're going to replace both front and rear upper control arms to allow camber adjustment, you would then take 9) as indicated in 10). Thus, at this point, replacing the rear lower control arms would cost you +1 in 10) and really be a waste. Quote Link to comment Share on other sites More sharing options...

After rear engine RWD, time for a new experience. Going to see if an old dog can learn any new tricks. Peter Quote Link to comment Share on other sites More sharing options...

CWeber Posted March 19, 2013 Share Posted March 19, 2013 FWD can be a blast.. just keep your foot in it and you can pull yourself out of all sorts of rear end slides.. haha I'm envious of you guys going to sebring (especially after watching the 12 hour race there this weekend!) ...it's on my bucket list... some day!

Trying to not spend truly prodigious amounts of money this time around. I will let you know how that works out. Nothing cool just an ex SSB Civic Si but at least it doesn't have the BMW/Porsche tax on parts. Peter Quote Link to comment Share on other sites More sharing options...

CWeber Posted March 20, 2013 Share Posted March 20, 2013 lol... ..considering we have both FWD and RWD race cars in our stable... I can tell you both have their fun factor... and obviously if you set up a FWD correctly, it will be plenty loose in the rear end ..plus you gotta love the cheapest way to get the back end on a FWD nice and loose --> over-heatcycled tires in back taken off the discard pile!
