i am not sure whose these were i saw it and liked them several years ago

The Camaro irs looks pretty compact. If you had a spare frame, mocking it up would be easier, or even somebody’s junk rear frame (they show up on CL now and then). Plus upgrading it later on would be easy(hammerhead, etc.).

If you plan on a roll cage, hacking parts out of the frame is less of a structural issue.

I was supposed to get a 76 frame a week ago... it didn't happen. Fortunately, I have a lift so doing this under the car isn't terrible at all - and in many ways better because you don't get surprise with things that you didn't remember being in the way. I still think the hardest part of this will be widening the front track to match the rear.

 

[bobs77vet]

can you alter the track by using different offset wheels?

yes and that's kind of why I'm doing it. When someone uses deep-dish wheels, the leverage at the edge of the wheel does nothing good to the bearings but putting the hub in the center of the wheel, it puts far less stress on the entire unit. With that said, I still think I'm going to mount C5 suspension on the front - so the track-width issue is pretty much solved. Now to get the car down to a sub-3000 lb fighting weight

i just adjusted the ride height on my C5 that front end is certainly easy to work with

I respect what vette427 has done on his Vette, and would love to design my own but my learning hasn't hit that point (heck, I'm not even sure I see the mountain he's climbing yet) so I need to copy what the people smarter than me have done... with that said, I'll put this out there to hear thoughts. I'm thinking of just using the a-arms, springs, loaded spindles - but swap them side to side (making them rear steer) and use the stock steering box. Then I get the width, geometry, forged control arms, brakes, unitized bearings but don't dive into figuring out steering.... probably something painfully obvious, but it's my current thought.

i cant help on that one ......i mostly install engineered products. i can do that pretty well

I've never done either one but I did sleep in a Holiday Inn last night.

My impression is a C4 front suspension is easier. I think the engine cradle from a C4 is a separate part and can be somewhat "grafted" onto a C3 frame. At least it would give you the positions. Maybe a C5 is the same?

The Detroit Speed setup uses C5 spindle uprights (I think) and is a bolt on deal. It is a rear steer, not sure of the rack used. But maybe it will give you some ideas.

Just throwing this out. IIRC the C4 front knuckles have the spindle positioned slightly rearward of the knuckle/balljoint centerline for caster purposes. My understanding is that this feature would be a disincentive to converting a C4 suspension to rear steer.

I'm not familiar with C5 and later suspensions to see if the Corvette group did a similar thing to the C5 and up pieces. Given that Detroit Speed has done a rear steer C5 conversion, my guess is that the C5 spindle is centered.

I welcome any corrections to my understanding of these parts.

my eduguess is you're right. I've done a lot of searching and my googlefu is just not finding anythin... Fortunately, I have enough dampness behind my ears that I'm willing to buy the parts and give it a shot - at best I've come up with a suspension system that doesn't cost 25k, at worst it's entertainment. That said, I may run the stock suspension this summer while I collect parts (and really deep offset 15x12s so it doesn't look absolutely silly).

phewwf! Just went through all 25 pages! Your progress is too fast for me :crylol:
Touching on the camaro IRS... Go for it, but definitely get a junk frame to fit it to first. I regret pulling my car apart to do this when I could have just gotten another frame and kept driving it. Also way easier to check for fitment. Drive it sooner than later, it looks like its going to be a blast as is
Oh, and Im not even sure I see the mountain that Im crawling up lol

But I appreciate you climbing it first - even if I become that soft thing you land on if you fall

 

[SuperBuickGuy]

for the record, I'll never use vette panel adhesive/filler again.it works for adhering, but it gums up paper... there are better options out there.
Anyway, boring post, but it's going the right way





it also sags, a lot
it took 2 pads per panel to knock it down


I really hope this works - kitty hairedited


it cooled off again, so back to diesel planning

at some point you've just got to ask yourself if you have time to do this - or in this case, is it worth it.edited The hood I bought is flat, so I need to cut all the supports and put the part that rises at the fenders then refiberglass.edited The scoop needs to be lengthened.edited All of these things I've done.... but I simply don't feel like it... so this is happening

 

[SuperBuickGuy]

I think it's going to work, kitty hair

it's going to require some sculpting, but it should be strong enough .... crossing fingers

and other side


second layer

interestingly, I got closer the first time on the hardest side

this should be the final base coat, all the rest are going to be gold coat that get sanded to make this smooth


and I started fixing the wheel well, they're actually worse then I thought... the edge - isn't the same angle to the other side - what that means is unless I fix it, one side will have the tire seeming to stick out further then the other
​​​​​​​

I should be clearer - the next step is take the doors off, finish removing paint on them and the paint that is still on the sails... but all of this fits into starting the leveling coats - first with gold filler then sandable primer, then primer, etc.. etc.

 

[SuperBuickGuy]

a lot of repetition, but here we go



the whole point being it's going the right direction



anyway, I forgot to order 80 grit and didn't stop to get the final coat (evercoat 125) from the paint shop... truth be told I hate going there because they are way too expensive... but sometimes there is no choice. Let me for example, I needed 2000 grit pads to color sand, they sold me 2 for $50. look up what it really costs and you'll see why I avoid them. Too bad for them.

nice.....the MGA has wood floor boards easily made....but I bought them.....and i splurged on a pre terminated brake line kit....

sometimes its just easier to push ahead with the path of least resistance. and have some more fun with something else.

 

[SuperBuickGuy]

the blending the front, flat is what I wasn't looking forward to doing - then this one came along at about $200 off.... yeah, onto the next task.

 

[SuperBuickGuy]

parts fell off
back glass


passenger door and driver's door


nothing remarkable except that someone used silicone to keep the shims in place


this corner looks like someone worked on it with a paint brush.... it concerns me slightly


all of this to fix hinges and to finish stripping the paint.edited In the end, these will probably be crank up windows... both motors are toast, the switches don't work and frankly I'm capable of rolling up a windowedited

 

[bobs77vet]

are you putting in a removable rear window?
