Kit differences - RT Inboard & RT+
Mag1caltrev0r - 20/3/08 at 08:57 PM

I'm sure this has probably been asked before but I've done a search and I can't really find the answer.

What's the difference between the RT Inboard and the RT+ kits? There appears to be a difference of around £500. I've had a look at the kit contents but I'm struggling to work it out.

Thanks

I don't know for certain but I think it is the fact that the + is fully Rosejointed...

Cheers Steve, I might have known you'd be able to help

That rings a bell actually from when I visited MNR. So how does being rosejointed affect things? It's my understanding that it's better for track stuff but not so good on the road? I'm not really sure, can you explain in more layman's terms?

Cheers

Hi Magic Trevor,

Yep, Rosejointed suspension is probably too hard for road use (especially on UK roads!), I think the IB is probably a good compromise (can't tell you how it drives yet tho...)

If you want to come over and take a look sometime, we're only up the road in Swindon - we're building an IB as well, with a Pinto engine....

Cheers

doesn't the + use cortina fronts and the RT sierra?

RT inboard also uses front cortina uprights, its light(raceleda) and a lovely looking bit of kit.

I'm not sure if it's changed but the RT+ also had T45 instead of CDS for certain parts of the chassis.

I've got to be honest though, the rosejointed suspension isn't too hard. Do you honestly think those solid bits of rubber bush are going to give that much?

RT+ has inboard suspension and rosejointed, and it does use the cortina uprights.
The IS is definately worth having, but the rose joints depend if you plan to drive it on the road or track.

RT Outboard suspension is sierra.
RT inboard & RT+ are cortina (=better geometry).
RT has polybushes (better on uk roads)
RT+ has rosejoints
RT+ has CDS rollbar (lighter & stronger)

mine is RT inboard but has CDS rollbar upgrade
I could change wishbones to rosejoints & it would be the same as RT+

You mean T45 rollbar. Anyone want to comment on the Super? T45 everything I believe.


Mag1caltrev0r - 21/3/08 at 09:13 AM

Nice one, cheers guys.

The car (when I eventually get round to getting one!!!) will be, at first, mainly on the road. I'd like to think that it will be half and half but that might just be a pipe dream (T45 or CDS )... pun intended... I'll get my coat


Agriv8 - 21/3/08 at 09:38 AM

Think the web site will show this ( or may be a sugeation to marc a comparison table )

Anyway just thougt I would add that.

Who told you that Cortina Uprights had better Geometry???

Hi Mate!
If I were you I wouldn't go for the Rosejointed suspension package, but I would go for the Inboard and be confident that you were buying a good all round car!

If it were me I would try and get an "in between scenario"!
I don't think there is a need for the entire package to be Rosejointed. It would be very simple to have 50% or maybe less that would achieve the same results. I think this would benefit in two ways, one would be cost and the second would be longevity of components...

Yes I did mean T45 Rollbar, just tired! - old age
inboard doesn't have to have raceleda uprights, cortina
ones or MNR's own can also be used, with or without the
raceleda hubs, discs & calipers.

BUT, be very wary of going for Cortina parts. There haven't been many and Marc doesn't always carry the machined parts - ask me how I know!


GeorgeM - 21/3/08 at 10:02 PM

I agree, i've got mnr uprights, but otherwise
all raceleda. If I did it again i'd have the
raceleda uprights as well

Except one idiot who had Cortina... i.e. me.

What's wrong with cortina uprights? I have a pair all cleaned up and painted waiting for the big day.


Agriv8 - 23/3/08 at 10:53 AM

nothing at all - not as light as the raceleda ones I belive, the raceleda uprights have a geomitry flaw removed ( a very very minor one)

regards agriv8


marc n - 23/3/08 at 10:50 PM

nothing wrong with std cortina uprights, just hard to get hold of , we used to stock pins off the shelf to adapt to our wishbones but now they are made individually as we dont see many usable cortina uprights these days,
we tend to use either our own version or the raceleda ones as we can use different hubs and steering arms to alter scrub and ackerman

cheers

Thanks, everyone for your help, I guess I'm probably right to go for the RT Inboard.

Marc/Chris, as Agriv8 has suggested, maybe a comparison chart would be a useful addition to the website? Or you could have like many car manufacturers have and list what the kit has 'in addition' to the cheaper kit?
