Fibreglass boot lids

[redcar]

Mark,

Some photos of the flossman fitted to my car.

The flossman is a replica in GRP, the quality is exceptional, its very light and a perfect fit! I figured that for such a sacrificial part (it will get scraped) its perfect function counts more than its looks or material composition. The lip extension is hollow, making it almost as light as the CF version.





Not too happy with the coarse screws holding the CF canard plates, so i will get some nice stainless countersunk ones. But as it is they are very functional and fit perfectly!



Lots more to do still!

Andrew

Got any pictures of underneath and how far it goes back?

[Demlotcrew]

I do, it goes to the front crossmember where is attaches.

Martin @ http://www.raceparts.biz/products.htm sells these if you are looking for one.



I need to trim some off the sides as the under-tray reduces lock, I have to make some track lock stops too. You can see how wide and how far back it goes!

Andrew

[Demlotcrew]

Its huge!

It will make a big difference. Have you heard Karan's feedback about his from yesterday?

I suppose you are going to flat floor the whole car now as the car may be a bit oversteery otherwise.

[Demlotcrew]

No not spoken to him, did he like his one?

What does a flat floor have to do with oversteer?

[redcar]

No not spoken to him, did he like his one?

Speak to him. Made a pretty noticeable difference from what i understood, sitting in the passenger seat.

What i meant was, your car may oversteer somewhat with only that part. So i was asking if you are going to flat floor the whole car so that the effects are spread evenly along the whole car and it remains "balanced".

[Demlotcrew]

Thats not what a flat floor does.

The rear will be compensated with an adjustable spoiler which is currently being made by TrackM3, should be ready for the end of the month.

the bits on the sides are called CANARDS or Dive Plates

you can normally get them on Ebay if you do a search on them.

I have them on my E30 so they help with front end grip and turn in; also with stabilty at high speed when combined with the rear aero I have on the car:

Planning to finally fit my front splitter next week and thought I would get some CANARDS.

Cheap they are not.

[Demlotcrew]

Mark, what splitter are you fitting?

[Hoobs]

Same as this one.



Anyone tried rear diffuser on e30?

[Demlotcrew]

Mark it has built in canards at the sides.

Clearer pic

I know, but being a bit of a tart, I was looking at replicating the additional 2.

[Demlotcrew]

yes but look at the gaps at the sides where the splitter meets the valance, thats horrible! The upper canards are just for show, they wont do diddly squat!

You need to profile like this;



I would spend time on doing this rather than messing about with fitting expensive canards.

Andrew

[Hoobs]

Have you been peeking through my windows?

We came to same conclusion about the profile and actually chopped the whole thing in half to narrow it. It now actually sits as in your pic and looks a whole heap better for it.

[Demlotcrew]

Oh dude

You need the width! Oh well, im looking forward to the photos anyway. I guess I'm lucky with the Hartge front lower valance being so wide at the sides.

Andrew

[Hoobs]

We're not talking a massive amount. It was a case of wanting it to sit right but also wanting it to be properly fixed and able to cope with the amount of force it must generate at speed. The pics will explain it better than I.

Have you modified the rear or looked at using a rear diffuser?

[Demlotcrew]

The rear is still work in progress, much like the rest of the car. It will have a flat floor

[Hoobs]

It will have a flat floor

We were looking at that but still have a few other mods to consider first. I still want to lose a chunk more weight (off the car and my waistline) too.

The fact that I still have the sunroof needs to be sorted soon. I saw the carbon fibre replacement but am hoping a cheaper / fibreglass one comes up. Either that or I remove the whole roof-skin?

[Demlotcrew]

Im keen on getting a CF sunroof panel and TrackM3 is working on one for me. Im not too bothere about that as weight, there are so many other areas to loose weight from.

Andrew

[Hoobs]

there are so many other areas to loose weight from.

True, I'm trying to shave a bit off each week.

How light do you think is achievable without getting silly?

[Demlotcrew]

Im not sure really, I have yet to weigh my car so I cant say, but i have gone light weight club sport.

[ross_jsy]

If it is just a track day car a fibreglass/carbon blank is going to be fine but if you ever enter a blue book sanctioned event it won't pass scrutineering. You need a metal blank.

A local guy makes blanks for e30's. Formed in all 3 dimensions rather than just a flat blank so it follows the curve of the roof and with a lip so you can tack it in place. Don't have any proper pictures but you can see it here:

[Hoobs]

I enter sprints so I guess metal is the way to go. Any idea on weight you've saved?

Weighed my old battery today - 16kgs! So that 11.5 kgs I saved with a battery swap!

Redcar for once is right.

Running a flat floor in addition to the front piece that you and I have moves the lower pressure point further rearwards under the car.

Running just the bit that we run at the front although massively increasing front end grip and downforce of the splitter can actually cause a pivoting moment around the front wheels lifting the rear up a little....

[DasChin]

Andrew

oi you calling my canard crap andy?!!

they are not ideal. we tried to widen the footprint and catchment area of the lower splitter with the m3 evo lip. the top ones are less than ideal but we have closed the gaps to help with cathicing air and helping turn in/braking front end stability.

it has helped a bit as I noticed better turn in at brands straight away notably in surtees and clearways where you are carrying speed and turning.

its not F1 after all!

that front lip spoiler form Martin Hollands is a lovely bit of work and what I might go for next

[Hoobs]

Can I ask how much camber etc you chaps run at Brands?

[JackLeach1]

How cool is that
I was really refering to the black and white E30's with the front air dam mods.
