[trackday_prep] My 205 GTI-6 Supercharged Track Car

DOH,

 

well we are just going to weld it up and see how it is

[SwedishBob 24 1 Cars]

Have done the same operation with my bulkhead. You can find pictures in my project thread.

[Spiky 37]

cool, just had a quick look at yours, nice job

 

forgot to add, mine will be a square box section to fill the hole

Did the same on mine in the end too. It has definitely put my mind at rest being able to have the engine and shafts running in the right position, without touching the manifold as i'd always be worried about the welds cracking if i had it re-angled!

That 205 is smart

[Spiky 37]

We did more work on the car this morning,

 

tunning and strut ops done now, just to need to get some etch primer tomorrow to sort the the new bits, then i will go mad with white smooth hammerite

 

 

 

 

one of the bolts had snapped on my gearbox mount, so welded on a new bolt

 

 

 

 

Welded up the cracked exhaust manifold

Nice work spiky!

Hi, where is your project thread ?

 

I'm wanting to do the same welding to my bulk head as well.

 

Cheers

Here it is.

Spiky, i may have missed it, but what's the idea with putting the ecc. top mounts above the strut tops as i've seen you mention somewhere?

[Spiky 37]

give more travel for my shocks

[205freak 7 1 Cars]

Nice work you´ve done in your car, awsome job!!!!

[Baz 421]

give more travel for my shocks

 

It won't though, it'll give less if anything as the ride height will be lower, wheels will be tucked up further etc...

[VisaGTi16v 1]

I still dont see how it can be remotely safe either. With the eccentric/standard top mount underneath as per normal, the upwards stress on the chassis is distributed around the entire diameter of the top mount. With the eccentric top mount on top, the upwards stress is taken completly by the 3 washers underneath the car on the bolts holding it on, I just dont see how that can be safe long term or if you hit a big bump. Strengthening the chassis from above with plates makes no difference at all as the stress point is still the washers underneath.

Not with fixed height dampers/springs but with coilovers you can adjust the height to the previous position and then have the same ride height but increased travel.

 

I do agree with Visa's comments about strength, it doesn't seem right, however a few people on here seem to have no problems.

[Baz 421]

As above, the plates are to strengthen the shell, and stop the turret tops from doming.

I don't follow, you can't change the top spring pan position, (can you?) unless you do what Spiky intends, and even then you can't change the overall length of the strut unit itself, so i fail to see where the benefit is.

You can run a lower ride height without compromising suspension travel.

[Batfink 201]

Maybe its not suitable for rallying but it worked fine on the 205 that donored its suspension for my racecar.

[Spiky 37]

dont worry guys, it's all going to be safe.

 

i will be using 6 evenly distributed bolts on each top mount, with thick wide washers under each to even distrubte the load

 

if it was a rally car, i would be slight concerned and re-enforced it a bit more, but mines a track only

 

i WILL get more travel as to regain the same height i will heighten the bottom spring pan giving more travel on my insert, while havign the car sit at the same position

Yep, as is said though it will compromise suspension travel as a lower ride height does just that!

[Batfink 201]

but running longer springs for the same rideheight will reduce the risk of going coilbound (springrates being equal)

It works fine. Not sure mine even ran with 6 bolts (colins adding more) and that was thrown hard against the curbs without any failures.

[VisaGTi16v 1]

On the subject of safety, have you moved your swirl pot so thats its not next to you in the cabin yet?

[Spiky 37]

are you telling me thats not safe??...lol

 

that is a job to be done in january

[maxirallye 2]

Yep, as is said though it will compromise suspension travel as a lower ride height does just that!

 

If you want to run at a lower ride height you wind the bottom platform of the coilover down, you will eventually run out of damper travel, and run on the bump stop. If you run the top mount above rather than below you can wind the bottom platform back up for the same ride height, and gain a further inch in travel.

 

Can I mail someone a photo of my setup to add to this post, I have taken this one step further..
