New Lambo undressed...

This was linked on another forum, but I thought it was worth a general look. Yes, it's expensive... No, you'll probably never get your hands on these parts... But it sure is an interesting design.

Thanks for the cross post, interesting stuff. I really like the hydraulic lift on the coilovers idea.

Like others mentioned in the comments, I think the front tire size mentioned is incorrect. The alleged 225 tire on a 9" rim in the pic doesn't look like it belongs on hellaflush.com.

Give you an extra 3/4 to 1" of lift. On a push rod set could give you more if designed with that in mind.

Thanks for that!

That is the sexiest suspension I've ever seen...

[LUACE]

Extremely nice!!! I am little surprised about the front tire... At 225, it seems very narrow for a super car with suspension that should be able to handle anything. i would rather see a 295+.

I love horizontal coil overs, it just looks like business.

A 295 wouldn't really do anything positive. It wouldn't track as well down the highway, it would diminish the car's sharp and precise steering feel, and it might contribute to oversteer. Simply put, thanks to the characteristics and weight distribution of a mid engined car big front tires aren't needed.

I think TCIs (hilarious!) point was that a 225 section tire wouldn't fit a 9" wheel the way it's pictured there....

Ray how much of a difference do you think a cantilever rear coilover setup would make in one of our cars with a live rear axle? Would the reduction in unsprung weight make a noticeable difference and are there any side effects like poor ride quality due to short shock travel?

[preston]

A rocker arm setup on a live axle is primarily a waste of time IMO because you already have a greater than 1:1 motion ratio at least if you have mounted your shocks behind the axle. So you are only saving the unsprung weight of the coilover itself and compared to the 300 lb weight of an axle and its wheels you are completely turd polishing at that point. That leaves only the advantage of packaging, or in the case of a couple pretty awesome Mustangs that were put together lately, exotic looks. Although pretty trick looking, all the Maier style setup really achieves is moving the CG of the coil overs higher on the car and to intrude on passenger space (not saying by any means that is not a worthy price for looking cool). The older TCP/Chris Alston/Ultimate Perf rear suspensino that mounted the coilovers down low on an underslung chassis had more the right idea, but adapting it to a standard unibody just meant you were adding weight.

I did have a design once that used a wishbone/a-frame/satchell link style suspension where I had put the coilovers to be rocker actuated and mounted on the rear seat bulkhead area. This would allow you to have no substantial chassis structure of any kind behind the rear seats. Talk about weight savings. It would only be good for an Atom/T-bucket/hot rod style of car though, so it wasn't anything I could use but I still like the idea of it.

What a great link...could spend a couple hours checking it out.

Slightly related, I work next door to Lamborghini Dallas...this was parked outside in the rain yesterday!

Hilarious indeed!.......If ya look reeeal closely it's a 255/35/19

cool link, thanks!

Work of art! Thanks for sharing.

Common misconception... There is no reduction in unsprung weight...

Remember, if you put a jck under the car and give it one pump, anything that goes up is sprung weight. You still have the bellcrank, links, and 1/2 the coilover in droop. Unsprung on an inboard is very often heavier than a simple outboard coilover (of course the percentage increase on a stick axle car isn't much... Shock travel can be increased with the cantilever due to motion ratio of the bellcrank. The main advantage to remote mounting is putting the coilover (bag, etc) someplace where it fits better....

[19,69camaro]

Damn I missed this before thanks for the correction. I am still considering a pushrod setup but now for different reasons.

It should make packaging the rear exhaust a lot easier since I went with a 4-link with a panhard bar similar to a quadralink. The real reason I am considering it is that I am minitubing the rear right now (69 camaro) and there isnt a whole lot of frame left to attach the panhard bar mount to. I would also have to throw a crossmember in there to attach the coilovers to. Granted there the car doesnt have quarters on it right now, but even with subframe connectors there is a ton of flex.

I was thinking that if I replaced about a 1 1/2 foot section of frame with 2x3" .125 tubing I would have a solid foundation to mount the panhard bar and a crossmember to. It would also make tubing the car tons easier because I went with fabricated tubs.

Now since the rear suspension is a 4-link and I was never planing to have a rear seat I made a very strong crossmember to support the ucs's that takes up the space where the back seat would have been. This would easily support the coilovers if they were mounted to it. I look at it as a way to redirect the force from twisting the rear frame. So instead of having a vertical force it will almost be lateral.

Speaking of Lambos.....One of the guys on my boat site got new exhaust for the Lambo he just bought....
