I'm looking at aluminumdriveshafts. I've done a search and it appears the majority of you guys love the Sydershaft.

It's seems like most of you prefer the 3.5" driveshafts over the 4" driveshafts.

I do plan on supercharging in the future, so a strong driveshaft would benefit. I'm not certain if I will lower the car yet.

My one question is: What's is the difference between the shafts with a new pinon flange, and the shafts with the adapter plates?? Strength issues? Vibration issues? It seems to me the pinion flange would be a more difficult install due tosetting thepre-load on the pinion gear (don't want to over or under tighten). Whereas and adapter simply bolts on.

Here's a list of shafts I've found:

Powerhouse: 4",adapter, $700
Shaftmaster: 3.5" AND 4", pinionflange OR adapter, $450-645
Currie: 4",pinion flange/adapter ???, $700
Spydershaft: 3.5"-4" tapered, pinion flange, $520
Coast: 4", adapter, $580
Dynotech: 3.5" pinion flange/adapter ???, price???
LFP (Lightning Force Performance), pinion flange/adapter???, $480
Steeda: 3.5"-4" tapered, pinion flange, $650
JPC: 4", pinion flange/adapter, $750
Findanza: 3.5", pinion flange/adapter???, price???
Lakewood: 3.5", adapter, $640

I'm leaning more towards Sydershaft, Steeda, or Shaftmasters. Shaftmasters 3.5" with pinion flange is $595, with adapter is $645. Spydershaft seems to be the most liked and doesn't hurt the wallet too bad. Steeda is definitely a quality product, but pricey. Don't know much about Shaftmasters.

I need input guys.

Thanks.
