    He meant the more angled the shock spring unit is the less effective/efficient the spring is. As the suspension compresses the shock works towards becoming horizontal thus the opposite of rising rate, which is stiffness INCREASES as the suspension compresses. Your effective spring rate will get less as the suspension compresses ... but so did the standard design, just you have made it slightly worse. The effect of this is that you have to run stiffer than necessary springs making slow speed ride uncomfortable.

    Since you have gone crazy with this car you could include pushrod suspension in the design creating proper rising rate ... now that would be cool and you could mount the coil over nice and low so that the C of G is improved!

    I should get my box of LEGO Technic back from my nephews, I used to build all kind of cars with working suspension 30 years ago with ingenius designs, I can make a LEGO prototype. But seriously, either too much work or life is too short, the suspension right now does an excellent job of holding the frame of the ground :). I want to get this thing on the road and maybe then improve as time and money permits. Somehow I don't think I will be driving it this year, many things still need to be done and build.

    Hey Bert, any updates since your last post? It's a stunner, I would be very afraid to alter original parts, but you just go ahead an do it, amazing :)

    Thanks!
    Yes, I installed all the new steel brakelines and then filled and bled the brake system. At first that didn't go to well, the front were done in 20 seconds with the easy bleeder but no fluid went to the rears until I totally turned anti-clockwise the knob on the brake bias valve, that is releasing the spring that is inside. Only then fluid went to the rear and I could totally blead the system. But if I turn the knob on the bias valve all the way clockwise, that should give maximum rear bias, it barely brakes. I spin a rear wheel (jacked up) and have to put large pressure on the pedal and then it barely slows down. With the knob released there is more pressure to the rear, that is not the way it should be. I did connect the bias valve the proper way. Will see about that later when testdriving when the booster works.
    I started to make the indents for the shilelds in the front fenders and the rear vents behind the rear wheels. Where metal working skills end filler does the rest :). I'm thinking of putting the airfilters behind those vents and use the side air scoops only for the intercoolers. I realise the vents are facing the wrong way for that but air can also be drawn in through the vents in the bottom and the vents below the rear bumper.
    Coming weeks I'll be doing further smoothing the body but it is hard to show progress in pictures.

    Ok ok! Out came the angled grinder today again. It is a perfect spot for letting in enough cool air, will mount cone airfilters behind them left and right. Replacing the fuel filler will be an interesting problem though, where it is on a GTO is a bit low and will need sharp bents to go to the tank. The lower air inlets will go straight to and only to the intercoolers, will have to make alu ducting or something.

    Another idea I have is to reinforce the fiberglass roof panel with 2 steel bars from front to back and a cross like this: lXl and reinforce the front and rear mounting points on the car so that the roof can be bolted on with a large allen bolt on each corner. Will take a bit longer to remove and install the panel but the car will be much stiffer with the panel on.

    The original rubber seal fits in the round hole for the fuell filler neck. Already modified the fuel filler to reach the tank. Need to rob some japanese car from it's hardware for the fuel filler door, a hinge and a remote cable operated lock. The lever for the cable will be in the door post where the trunk lever is, it's only 50 cm distance.

    Sort of wondering if converting this car to being a fibreglass one might have been easier ... probably not?

    Yes amazing.

    Bert,

    Yes!

    Aren't you happy now that you did that job? I do apologise for the harsh language, but hey, it worked and you got to it:)

    For the fuel flap lever, maybe try to get a lever-box from a GT4: there are 2 levers next to eachother, narrower than the original one in the GTB/GTS. The whole box is a little wider, but it'll look 'standard' (without knowing how the 288 looks in that detail)

    I'm really happy you decided to do this, the result will look so much better!

    Thanks! You and others are too kind. I am sure there are a lot of people who think my workmanship is crap but are too polite to post! I know I'm far from "Newman quality" or Will de Groot with his scratchbuild Maserati roadster but you can spent 3 years or 12 years on a project. If I ever planned to sell this car I wouldn't post pictures of the build but only finished parts covered in nice shiny paint, so nobody knows what's underneath!

    For a fiberglass car, all the work I did until now would only be the plug. Then mould making, parts making, seeing how to attach to the steel, no thanks, I hate working with fiberglass and the result would be a disaster. In steel is a bit heavier but more solid. However I now have a solid rear end, a solid front end but basically connected only by 2 oval tubes. That is why I'm also thinking of reinforcing the roof and make it bolt on/bolt off.
    The fibreglass kits available all look wrong, it is not my goal to build an exact GTO copy but the car has to look good, not fat but voluptuous (is that the word). Also the kits are all for standard wheelbase.

    Thanks! It is an extra 40-50 hours work but who is counting? Yes it looks better and the extra air inlets come in handy. I ordered 2 cone filters that fit behind them above the wheelwell.
    Thanks for the tip about the GT4 levers! I was thinking (budget!) just a cable with a pull ring but will search for the nicer solution. Btw a GTO has an unlocked flap with a filler cap that has a (troublesome) lock.
    Everybody who thinks I'm building a GTO clone and be a pretender, I'm not but it is just that all the solutions they choose for the GTO are so good looking and are actually very good an useable for my car! There are $50 GTO badges oin ebay but the 308 badge will stay. Comments on youtube are far less polite than here and someone said I'm changing a 308 into something that it is not, well I'm modifying a 308 and so it will be a modified 308, no more no less. Putting a GTO badge on would make the whole car a fake and a joke.

    Make your supercar, spend your time to find the best solutions and then drive the damn car.
    You are NOT a pretender, you're an inventor...I wonder why Ferrari-design havent ask you to join them.

    Keep up this splendid work,

    Bert.....

    Wear eye protection. Don't play with your health, it's not worth it.

    I have only one functioning eye (not due to accident) and believe me, you don't want to risk it.

    Do you have so many headroom to spare? I think it will only make squeal noises when the car is torsioning a bit. Unless you could directly connect the |X| thing to the chassis, but I guess there's still rubber between it no?

    And watch for your health, I remember the previous accident with the Dremel thing on your nose (could've gotten into your eye!), I thought you would've learned from that experience :)

    Goggles completely snck because you cannot see anything, but I recently had a similar accident and thus I've now bought a full face guard thing. So much better than goggles and you can see and it does not fog up as quickly.
