jman093 Posted February 11, 2011 Report Posted February 11, 2011 Psychomatt, I would NOT put poly bushings in the rear suspension arms. They work wonders for the front control arm bushings and for sway bar bushings, but our rear arms HAVE to deflect laterally for the suspension to work right. The arms move outward and towards the rear of the vehicle as the suspension compresses. Poly bushings will bind and you're left with a stiff ride, unpredictable handling, and probably premature bushing wear. Bob, didn't you yourself say that you even bent some arms with polys in them? I know a lot of aftermarket companies use them in independent trailing arm suspensions, but trust me, they are not the right application. The GMPP trailing arms (if you can find some) are a great upgrade and use a rubber bushing and Bob's trailing arms with heim joints should be even better. But leave the rubber bushings in the Gen 2 lateral links (or get Bob to make some with heim joints:) ) Quote
BXX Posted February 11, 2011 Report Posted February 11, 2011 Yes, I have tweaked my rear lats with the poly in there. Potholes were involved as well. I would imagine avoiding potholes and uneven pavement and the binding would be kept to a minimum. But your 100% right, poly is not the best use of bushings for our rear lats and trailing arms. But its a step above stock as for stability before you have to spend big bucks on the rear arms I make. Quote
Venom Posted February 11, 2011 Report Posted February 11, 2011 I think the guys have pretty much covered the bases here for what you need. I do have the part numbers for the lateral arm bushings as well as for the front lower control arms (ES sells a kit with just the lowers only now) so if you need them I can dig thru the "Cutlass" file in my computer desk that houses all my receipts and notes. One thing I was wondering if you havnt already discussed it, what tires are you gonna run? All the suspension goodies wont really come alive without a decent set of tires. I know Im really being limited by the GM OE Hankook take-offs Im running now. I dont plan on spending a fortune on a set of tires, but its something else you wanna consider doing. Quote
BXX Posted February 11, 2011 Report Posted February 11, 2011 Bridgestone Potenza RE760 Sport. Problem solved on the tires:lol: Quote
Venom Posted February 11, 2011 Report Posted February 11, 2011 Naw, Yokohama S-Drives. 225/50/17s 300 tread wear and a 98W to boot. Quote
BXX Posted February 11, 2011 Report Posted February 11, 2011 They tested better than the S-drives foo! http://www.tirerack.com/tires/tests/testDisplay.jsp?ttid=104 Quote
Psych0matt Posted February 11, 2011 Author Report Posted February 11, 2011 thanks for the continued input guys, it's doing wonders! This weekend when I have some free time I'm gonna make up an order list and what I want to do and get organized so that when I deposit my bonus check on Wed I can start ordering things right away. As far as tires, haven't thought that far ahead, as that's the last thing that will need to be done. I still have yet to decide what wheels I'm going to run, or if I'm going to redo a set first.

Psych0matt Posted February 11, 2011 Author Report Posted February 11, 2011 They tested better than the S-drives foo! http://www.tirerack.com/tires/tests/testDisplay.jsp?ttid=104 None of those come in 245/50-16s though either Quote
Night Fury Posted February 11, 2011 Report Posted February 11, 2011 I'm running S-drives, they is AWESOME! Quote
KingVee Posted February 11, 2011 Report Posted February 11, 2011 Yokohama is ALWAYS a good choice, end of story. Imp558 1 Quote
Psych0matt Posted February 12, 2011 Author Report Posted February 12, 2011 (edited) Coilovers sleeves $18.80 x4 nuts $12.87 x4 bearing kit $25.95 springs $39.95 x4 (I could use some suggestions/help chosing, but I think somewhere ~300 is what I'll want) Mounts/fstb $per BXX shocks/struts (GR2) font ~$60 x2 rear ~$60 x2 2nd gen rear knuckles $40.00 ball joints ~$30 x2 tie rod ends ~$25 x2 These are the parts I'll still need help with. I don't know where to get these, or in some cases what to get (for example, the front bushing stuff, I'm just not sure). As well as any other add ons or whatnot. I'm gonna look up Chris' (IIRC) FFP poly dogbone write up as well and redo mine. GMPP (or BXX) trailing arms with rubber bushings $??? Gen 2 lateral arms with rubber bushings $??? rear STB $??? front suspension poly bushings (help?) $??? Total so far: $702.43, so with the other things I need I'm assuming roughly right around the 1k mark like I was hoping. If anyone has any leads on anything else I need, or any other suggestions/idea, go for it. I'm just planning all this out so that when I get my check deposited I can start ordering and acquiring parts asap. Anything I'm missing? Edited February 12, 2011 by Psych0matt Quote
Twenty Posted February 12, 2011 Report Posted February 12, 2011 I'm going to be running 425/300 springs F/R respectively. I'd suggest looking for a stiffer front pair since most of the weight is up there. Quote
BXX Posted February 12, 2011 Report Posted February 12, 2011 Matt, front and rear mounts will be 350 shipped for all of them. If you want the front mounts with integrated ftb mounts and the bar I would need another 120 shipped due to parts and welding costs. with gen 2 rear laterals, get the gen 1.5 22mm rear sway bar, slap some moog bushings on the sway bar and win! Quote
Psych0matt Posted February 12, 2011 Author Report Posted February 12, 2011 Can I still use a stock 3.4 stb with your mounts? I don't wanna go that route but I might have to, at least for now. I just gotta round up those last few things now. My other thought is if I came out and had you help me install maybe we could bypass shipping costs and I could buy you beers instead Quote

So I'm adding a gen 1.5 sway bar to the list? Gotcha Quote
Psych0matt Posted February 12, 2011 Author Report Posted February 12, 2011 Oh, and as far as the shocks/struts, I'll be ordering stock application ones? Quote
BXX Posted February 12, 2011 Report Posted February 12, 2011 yeah stock struts. Definitely the 22mm rear sway bar. And a vert bar won't fit my mounts. We can work something out. as far as shipping, the mounts are the same price lol. I do free shipping outta the kindness of my heart. I'm not making much on them as it is by selling them for 350. install is always an option, dr pepper is a known form of payment lol Quote
Psych0matt Posted February 12, 2011 Author Report Posted February 12, 2011 Well if you and possibly venom/al are still interested, I'd drive out. I'm still trying to decide if I should do the knuckle swap first so I'd have rear brakes Quote
stockgp Posted February 12, 2011 Report Posted February 12, 2011 how far are you looking to drop? i have a 3 inch lowering spring from birchmount and now i'm working on front coilovers. i'm worried that the struts aren't going to be able to survive long with that ride height. i bought gr2 struts for all four corners. are there an other alternatives? Quote
GOT2B GM Posted February 12, 2011 Report Posted February 12, 2011 Whatever you do Matt, don't skimp on tires. Your suspension will only handle and hold the road as good as your tires will allow. Quote
Psych0matt Posted February 12, 2011 Author Report Posted February 12, 2011 I'll get good tires, but I still have to figure out if I want to stick with the xrosslaces (and which ones) Quote
BXX Posted February 12, 2011 Report Posted February 12, 2011 I can hook up Matt with a nice discount on some Bridgestone tires:thumbsup: Quote
Psych0matt Posted February 13, 2011 Author Report Posted February 13, 2011 Picked up the rear knuckles (with temp trailing arms, if I use them) from Al last night for $40. First purchase made! Quote
