New approach

Hey I took a new approach to my winter project than i thought. Instead of starting with motor work i'm beefing up my drivetrain/suspension first. I already have mac shorties, flomasters, underdrive pullies, pro 5.0 shifter. I just got yesterday 2 1/2 off road h pipe, aluminum driveshaft, 3:73 gears, and eibach pro kit springs. My next investment is with axle. Now I dont want anything extreme because this is just going to be a street car with occasional uses at track, so... I guess i'd rather go big the first time and not have to swap again later. So I want to stay 28 spline,(dont have money for upgrade posi unit) and I want to know how the 28 spline moser axles hold up. Then I have to get my shocks, and I might go with kyb agx, the ones that adjust...who has these and do you think this is worth it going from the ones in between (not gr2's but next gasadjust ones). Thanks. Any other suggestions would be great, thanks.
 
Assuming you're keeping the engine pretty mild (under 300 horse), I wouldn't worry about upgrading axles. Spend the money on some nice full length subframe connectors. Everything else you listed there looks good.
 
It wont hurt it. He just means that if you are staying under 300 HP, then its not necessary. It would just be an unnecessary waste of money. If you are going to 400 HP, THEN get it. Understand?
