Part list

Can anyone tell me a good parts list to start with as far as SFC go and torque arms. I tried looking through the search but I was just wandering what will be good start with. I didn't see a big kit of all so I want to come prepared when I go order these parts. Probably looking at bolt ons for now can weld them later.(just need some decent support with the new engine to last till i restore the body)



Thanks,
Jon

Re: Part list

check out UMI performance, Spohn performance and BMR. They all sell subframe connectors and torque arms, some people prefer certain companies over the others, i personally like UMI.

I do not believe any of these guys sell bolt in SFC. You will have to use Alstons SFC, Topdown solutions (TDS) sells them, or use the "jegster" bolt in ones that Jegs sells.

Re: Part list

pretty sure hotchkins sells a suspension hit, shocks/springs/SFC/LCA etc but not a tq arm.

its all about price and preference. UMI has nice stuff, BMR does too. but i also like jegs. i pic with whats gona fit my needs as far as performance and price.
i mix match. i have UMI adj panhard rod, and lower control arm relocation brackets. i have handmade LCAs and SFC and soon a strut tower brace, but i have a jegster tq arm and TDS wonderbar.

Re: Part list

I personnally bought most all my components from Spohn. I have their panhard bar, lca`s and relocation brackets, torque arm, driveshaft, driveshaft loop, subframe connectors and wonderbar.

I have heard alot of good things about UMI, TDS, and BMR. As previously mentioned its a matter of personal preference and pricing.

Re: Part list

My method of thinking is go with manufacturers that work primarily with 3rd or 4th gens. J&M (Hotpart.com), Spohn, and UMI are good. I wish Hotpart was around when I did my rear suspension. I say go with weld in SFCs. Too much of a chance of play/movement with bolt ins IMO.

Re: Part list

weld in subframes are best but better ones are the bolt ins and then u get them welded in. same thing for the bolt in LCA relocation brackets. bolt in SFC and relocation LCA brackets are usually stronger and the regular weld ins physically since they have to spead the load over a wider area... but u just bolt them in and get them welded and theyre stronger... no play and no bolt elongation from twisting stress.

oh also forgot i have a jegster drive shaft saftey loop... add that too my list

jegster saftel loop is cleaner than the LAKEWOOD and is fully welded and designed for our cars. cheap too but it cant be taken apart to lower drivshaft like the lakewood since its all welded together... u would have to unbolt it from the floor pan. but i prob wont do that much so it doesnt bother me. buts its a very clean peice which is why i got it.

same goes for the TDS wonderbar. i dont have anyprobs with having to take it off to get my dual fans out. unlike sum other brands. they also look alil beefer the spohn or maybe he BMR piece IMO. also has 3 mounting holes compared to 2.

went with jegster tq arm bc i didnt want a tranny mounted arm. spohn/bmr have nice peices but are $$ i got mine used for cheap and its shorter than the BMR/spohn peices and gives me max clearance for my dual 3" exhaust.

weigh ur options and see wat fits best for u, price, preference, and what will work overall for ur goals/future mods etc

Re: Part list

I have all UMI stuff except I have the Alston (TDS) SFCs that are welded on. My UMI trq arm is a cross member mounted with a built in drive shaft loop.

Re: Part list

get subframe connectors first, and have them welded in.

then make sure you have good tires and shocks.

then you can start with he rest, i would get the LCA's and the pahard, then a torque arm.

Re: Part list

1 SFC's http://www.umiperformance.com/produc...ategory_id=113

2 Springs and shocks: I have no experience, mine are all stock.

3 Panhard since im sure you car is lower than stock and you'll center the rear. http://www.umiperformance.com/2021?category_id=107

4 LCA's http://www.hotpart.com/shop/index.ph...ct_detail&p=42

5 LCARBS http://www.umiperformance.com/2010?category_id=108

6 Strut mounts: Go with j&m or spohn

Edit: My opinion about a torque arm is this, if your making less than 350 horse, the stocker is fine, unless you want to change your pinion angle.

7 STB http://www.umiperformance.com/produc...ategory_id=167

8 Wonder bar: A stock one will be good.

Re: Part list

A 25 year old car will have "settled". Trust me, your car is not at stock ride height anymore, mine is down atleast .75-1.0 inch.
