Tubbing

[EmmaJ]

Stupid question time again....

Aside from the fact they seemed to have used ever GForce part known to man is there as reason why this is a bad idea?

Tubbed out to 325

Obvious things to state are:

1) I can't lose my rear seats, so if tubbing to this extreme means deleting the rear seats that's a no go.
2) Would still need to be road legal from an MOT POV

Thoughts?

Actually just found photos of the linked car on GForce's FB page and it would appear that the rear seats can be refitted afterwards so that's good news

You just loose the oem spring mount

Was Harry's car not tubbed ? Monkfish definitely did one before.


Issues ? Finding wheels that match and accommodate the the tyres. Potential rust issues due to our wonderful climate. Make sure all welding is well sealed up after.

Then the bigger question. Will 40mm of extra rubber really make that much difference ? It's a little bit, and bound to be better.

But it will make nowhere near as much difference as actual tyre compound

A decent drag radial of standard 275/285 width will still grip miles better than any 325 road tyre.

And the 275/285 road tyre simply bolts on.

Doesn't sound too bad? Does it still keep a similar rate of suspension travel?

[stevieturbo]

And looking at those rear end mods...diff etc looks great. But surely they arent leaving the rear end with those horrific shaft angles ?

That's asking for trouble. That diff needs raised a good 3-4" or so !

I'd love a 285 to simply bolt on but that's a mini tub which involve cutting bits out. I'm currently running a 265 so that's a big step from where I am and that's currently causing rubbing issues so if I'm going to do it, I may was well do it properly

Still not 100% sure if I want to go down the 1/4 route. I just want a more planted road car, which from all accounts a 285 would give me but I try to never settle for just good enough

Emma, as soon as its warm ill take you out in mine, think you will like the way it drives and puts
the power down

Cheers Mark, I might feel differently if I can cure the rubbing and it might be better once it warms up too! I remember my stock VXR wheels running 245 PSS's where very impressive grip wise when the tarmac temps were over 30c.

IMHO tyre temps and tarmac temps make a very big diffrence
I can go WOT in 2nd with no spin on tarmac over 20c and tyre temps over 38C
and even in 1st it grips

If you're on the Superleggaras, what are the wheel offsets, as that could be why you have the rubbing?

Even for the road, buy some proper tyres first. They are simple bolt on, and will make a huge difference.

Whether 888's or a proper alternative. The other thing about very wide tyres...dont forget, they will aquaplane much easier, and grip worse in wet conditions.

Although when buying the likes of an 888, or any high performance track type tyre. They tend to be slightly wider than their sizing states. So if you currently use a 265 and clearance is tight, make sure you buy a 255.

As soon as it's dry I'll whip a rear wheel off and have a look at the offset

[MyM8V8]

S800 ran 10's on his Ro. We need to know the offset (and / or back space) on his rear is you can remember Roger. I want to be getting around to doing this but not as radical as the G force car, which as Stevie has indicated, doesn't look quite right to me either.

[gsd2000]

I think roger ran 20x10j wheels with and offset lf +45.

Something like 285/30/20 tyres

Im sure rog will confirm

But if roger could do that will a roll then a tub which isnt as aggressive as the gforce tub and a full roll should in thwory all for 305 tyres

That's exactly what I want to know.

Mpss don't grip so well when its cold just found that out at the pod today spin up in every gear

Don't you know how to make them warm?
