Porterbuilt C4 Dropmember who has them/opinions...

Just wondering who all has one? Trying to decide if I go with the C4 member or the regular dropmember...

Who has one and what do you think of it... What are the pro's and con's vs the regular dropmember?

Anyone know if the shockwave's for the C4 unit can lift a big block and 4l80e trans?

There's probably only a couple dozen of them out there on the road that I know of (I have sold less than 100 of them). It has a more aggressive camber gain and 9 degrees of caster built in. The C4 components (88-96)significantly decrease the unsprung weight. If you run a shock-wave it will limit the amount of drop. With a 27" tall tire you will still be an inch off the ground when deflated. You can incorporate a coil-over also.

If you are looking for performance, this is a great solution. If you want a slammed truck that lays on a big tire and rides smooth... the regular Dropmember is a great choice.

We have also been working on a performance version of the Dropmember (Dropmember Touring) that uses a coil-over and maintains the C10 spindles and brakes... its main focus is performance as well and will have some cool features/options. Stay tuned...

I have a C4 Dropmember for a BBC/4l80e sitting in a box waiting to get dusted off (Vette parts sitting right beside it). Fall 2011 should be the start date on the assembly of those parts....

Re: Porterbuilt C4 Dropmember who has them/opinions...

I've got one. It's good so far, but I haven't spent much time tuning it. You can lose 60-100 lbs off the front end (can't remember the exact number) from the stock stuff. It could cost a bit more, but performance cost money right?

I didn't compare the steering units @ the time but I weighed everything else out (C4 vs. stock) & recall about 100# difference. This included 'loaded' upper/lower a-arms, spindles, calipers/rotors (12x1.25" D52 style iron truck stuff vs. 13x1.10" 2-pot alum PBR C4 stuff), 7" bag & Monroe shock.

Re: Porterbuilt C4 Dropmember who has them/opinions...

Humm, interesting... I was actually looking at the C4 member for the cost savings to be honest.. I can get 2 complete c4 assemblies (arms spindles calipers everything) for $300 through my day job... and can get the shock waves at a break too... Now to get just a brake kit that is comparable would cost me more then the whole c4 assemblies...

But I really want this thing to lay out....

Guess I have some decisions to make!?!?!!
