Hello to all . New to this site and my first post . I have been working on my car that I have owned for last 20 years  . 2012 had new motor built added around 200 extra hp over stock . New paint with fiberglass bumpers finished in spring of 2013 . Next was trans shop , total rebuild of turbo 400 adding 2800 3000 stall convertor . Also in 2013 had new leather seat covers and foam for seats , also had door panels and new motors and regulaters installed for power windows . This year will be working on brakes , suspension , front end  and wheel bearings . I have purchased most parts from Ecklers and now looking for extra advice on problems I may encounter and if others have used same parts with good or bad results. Suspension is 550 lb front springs with 330 lb fiberglass for rear . Bilstein sport shocks front and back . 1 1/8 anti sway bar for front and 3/4 for back . Poly bushings for A arms and rear trailing arms . Also have inner and outer tie rod ends and idler arm , rear adjustable strut rods. Brakes I have bought are Wilwood aluminum calipers with Wilwood drilled and slotted rotors . Have also purchased wheel bearings for front and back . Any advice or suggestions would be of great help . Thanks             

Sounds like you are building a monster.  Wow! 

Welcome to C3VR! 
Front springs might be a bit too stout, rear one is a little stiffer than stock, but might be ok. Everything else looks like good choices. If you have never done rear spindle bearings on a '63-'82 Corvette, you might consider paying someone to do them for you. They are pretty tricky to set up properly, and require some specialized tools. They can be done by a fair mechanic, with patience, and the right tools, but if they are not set up correctly, the possibility for early failure is great. Just my .0002

I hope it does not turn into a monster  . Just looking for more of a feel and power that would have come stock with a 1970 LT 1 with the F 41 suspension and upgrade brakes option .  

I hope the front springs will not be to stiff. Was all bought from Ecklers as a package they call the premium street and handling kit . I will be hiring a good mechanic to do a lot of the work . Found someone who has owned and worked on c3 vettes  in past. Takes pride in restoring old cars and I feel he will treat me fairly and do a good job . Thanks for your 00002 all help will be needed.   

I say put it together and drive it! Get at least 500 miles on the springs before deciding they are too stiff. The coils will break in some. I have no idea if fiberglass leafs "break in" or not. With the extra HP you will probably need an aluminum rad. Maybe even a pusher electric fan up front (keeping the mechanical in the rear).
Got pics?

Thanks for reply Dave . I will try and see what happens with springs hope all will be good. I did put new rad in when motor was rebuilt also added tranny cooler with high stall convertor . I put around 4200 miles on last year no over heating problems . I do have photos in my profile as well in the registry still trying to figure out how to add more .  

I did the poly bushings on both my vettes when I rebuilt the front ends. I have no complaints. Although I have talked to many that used them and they said they got noisey as they get older. I would recommend putting grease on inside and out side of bushings before installing them. I have not had any noise with mine. Cant speak to the rear spring as I did an original back there. Many here have changed and seem to like them. As for the rear bearings and spindles, yes they can be a handful. I ordered new trailing arms from baers so I knew they would be trouble free and I didnt have the headaches.
Welcome aboard the group and ask questions and enjoy yourself.

Do you shop around or do you only buy from Ecklers?  There are lots of Corvette aftermarket suppliers/websites out there.

Hello Garry . Yes I have shopped around . When I bought parts for interior and body work I purchased from Corvette specialties . When I purchased the suspension and brakes I did look at quit a few different sites , prices were very similar on most sites . I did find Ecklers had all parts and I thought I would save on freight buy ordering from one spot instead of two or three for different products. Long way to ship to Northern BC .
