Hi SAU

Might sound like a noob question, but anyone with a carbon fibre bootlid can hopefully help

Thinking of buying one for my R33, i havent actually felt how light they are. My main concern is will the hydrolics on the side that open it up. Will the pressure in these ower power the overall weight of the boot anf possible warp its shape when the boot is closed?

Again sorry if this uestion comes across as a bit noobie but just seeking some assistance here.

Thanks in advance guys and gals

Not ADR approved but lol

Pure carbon boot (rare) on r34 no spoiler installed can be lifted with 1 finger , maybe 2 kilos tops

Thats bare no locks or brake light

Carbon covered fiberglass bare is about 7-8 kilos

Factory boot , damn heavy for the size lol

The strut rods will crack the fiberglass over time as theyre designed for steel and heavy , you can buy low pressure for carbon parts

The strut rods create a pivot point and the boot lid tries to fold where the rods stop , on r33 it wont be so bad like a bonnet strut is

Carbon is way stronger then steel But can be brittle and unless you source a pure carbon boot which cost 3 times as much the fiberglass inner part will be the failure point over time

But its really not a issue about closing and pushing it up the leverage is gone when its flat except where it screws in

If you cant find low pressure struts or someone to mod your current ones give me a pm

Mine are from usa

Rather than starting a new thread I thought I'd be a good bloke and post in here. Recently I've sourced a Seibon carbon boot lid for my R33 to use at future track days. I want to use this boot in conjuction with a light weight spoiler, however would putting the stands onto the spoiler compromise the carbon structure? This cause damage to the lid?

I know this is a bit noobie but any help would be appreciated. Anyone have any advice on this?

depends on the spoiler , mounts , how often the boot will be opened , how the boot will be attached ( bolts and ???) and if its pure track car , i take it its pure carbon inside and out ? does it have a frame on the underside ? will you be using the boot latch /lock ? or ?

In most cases unless the wing is huge and pedistals small you could prob bolt it on with a carbon or alloy backing plate

Is it time attack high speeds or drift or ?

High speeds big wing would shatter the carbon over time if mounted wrong ! A true seibon for sure ?? the fit should be perfect unless the car was hit at one point in time

A few options exist shoot me a photo of wing /stands and underside of boot lid and answer questions above

Hey champ thanks for the reply. Yeah it's a genuine Seibon product, from what I can gather It does have an underside frame.

It will predominately be used for a mixture of drift and circuit. Don't think I'll use a lock with it either as I can't really see a need for it, and my impression is this would also only help to weaken the carbon.

The wing to be used in conjuction would be a Sard mini GT wing (1400mm).

Which wing stands you can get a few types ? link or photo ?

Carbon is stronger then steel but can be brittle around drilled holes, cuts and of course shatters on heavy impact , i can take a ball peen hammer to a carbon speaker box 2 layers thick and it wont mark or shatter it so its stronger then it looks

I would drill bolt holes with unibit titanium slowly and lightly sand the hole with 240-400 grit rolled paper to avoid sharp bits and weak points the bolts should slide thru not to loose or to tight fit

A backing plate must be used but it depends on where it sits on the ribs under it , you want to avoid bolting thru uneven surface , or mold a kevlar plate to back it with wide washers embeded into the epoxy where the nuts sit , if its flat i have kevlar plates made already if your interested in a couple ? you can bond those on with tiger bond , kevlar keeps the bolts from ripping thru and is impact resistant , wont shatter

The lock area is strong but could use a kevlar backer as well if used a lot to get to pumps etc

A pure race car never street used ?? street use you need to know carbon is defect if you care ? sharp wing endplates are too

if its pure race car your going to have to put a latch of somekind to hold it closed ? Quick release dzus fasteners are a good choice and made for carbon, fiberglass etc , ebay or aircraft parts sales , race shops sell them , use stainless or titanium not alloy version they can shear off in crash

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
