loads of us have used 17" wheels and i still think they look good even tho iv used 15" this time but its a bit of an insult judging the
quality of build by the size of the wheels

Suprisingly for someone choosing to run 17's I do have a reasonable grasp of the compromises of running that size of wheel, particularly with
reference to unsprung weight and the lack of warning when approaching the limits of adhesion. However I do think that these drawbacks do tend to be
exaggerated to a certain extent by the advocates of the smaller rims. The fitment of larger rims certainly doesn't mean that a car is going to
handle like a basket case.
In my case the car is being built as a fun road car, and as such the public highway is not the place to be exploring a car's on the limit
handling, be it on 17's or skateboard wheels. I hope therefore to have fun safely on my ridiculous wheels, and if the need arises to push it
that bit further, rest assured it will be on a set of 13" minilites with Dunlop moulded slicks off the Mini in my Avatar

As I said, I estimate people either put form before function, OR, they haven't a bloody clue. Read what you like depending on your preferences.
I also said: IMHO which I'm entitled to, harsh or otherwise.
Cheers, Rorty.

Good for you! You put form before function, but intend fitting smaller, grippier tyres before you break traction.

Maybe if I stick it backwards through a hedge you will have to reassess your conclusion and put me in the 'haven't got a bloody
clue' category!

I'm going to fit 21" alloys

hi peeps.
hope everyone is well and enjoying the fantastic sevening weather!
i had a very nasty accident in a car with 17" rims, partly caused by the fact that my driven wheels lost traction and broke away without any
warning. admittedly, i had a bike engine in the car and i was a novice at the time, but you cannot escape the fact that a lack of tyre wall
flexibility was a major contributor. i spoke about this very subject at the time, but some people never learn.
why do track sevens and formula1 cars run high tyre walls?
even rally cars run 15s on forest stages.
this fashion for massive rims comes from touring cars. they weigh a good deal more than a seven and need larger wheels to accomodate larger discs.
sevens don't need big brakes, so they don't need big wheels, period.
loads of sevens are actually over braked, especially at the back. why else would people be fitting brake bias valves?
this argument has little to do with whether a car is run on the track or on the road.
i was travelling at 40 mph when my accident happened, and i certainly wasn't "exploring the limits of adhesion" or doing anything
else crazy.
you are actually endangering your life when you put a bike engine into a car that weighs 450 kg and then fitting 40 profile tyres.
apart from the issues of rotational inertia and the effect that has on braking and the gyroscopic effect of big heavy wheels and the effect that has
on steering.
rorty has a very important point to make, in that the fundamental principle of design is that "form follows function". he has been
diplomatic enough to say in my humble opinion (imho), so why the tough guy attitudes?
i, too, would question the integrity and safety of a design, if it contained obvious flaws. you would have to be ignorant not to.
so give rorty a break. he is only concerned about your safety, as am i. i, for one, would not want anyone to go through what i went through last year,
and i'm sure none of you guys would either.
kindest regards,
dom

oh er!
i think folks are maybe getting carried away here. rorty has imo come across as being rather harsh on those who do fit 17"s on their cars. i
think everyone knows 17"s do effect the way the car will handle etc etc but i think what some ppl maybe need to realise is not everyone is
building a 7type for track use or country lane thrashings etc.
my 2p worth anyway.

Exactly. I'm not going to drive my 7 like a crazy foreign taxy driver. The last thing I want to do is die. That's the whole point of life,
not dying.

dudes.
if you're planning on using your seven for doing the weekly food shop, rather than blatting around on b roads, it doesn't really matter
how you set the chassis up, does it? just be sure to stick to the a roads and motorways and try to avoid going faster than 30 mph around
roundabouts.
should be fine then.
kindest regards,
dom.

dom ,you make me laugh.the big wheels can hardly be to blame for the 10 miles that you got to do in your car before bending it and to say you wernt
giving it any beans when it spun out brings tears of laughter to my eyes,you make out that they have no grip at all when in fact they do have plenty
of grip and they can be caught and drove sideways just not as nice and easy as 13" or 15" wheels.
this of course,in the lame ass way,is all IMHO

so then o mighty sages of all things handling, if i were to be looking to get a set of 13/14" minilite splitrims, what size tyres should i be
looking at putting on them? what size rims should i be looking to get?
iirc, the 185/70/13s that were on the donor give a rolling radius within 3/4 mm of 205/40/17s but would guess they would need to be slightly lower
profile side walls, to take some of the wallow within the tyre out. what about width? i've picked up that narrow is best for the wet, but what
about dry?
i am your clay, mould me
not with your hands though

Just remember this is a debate and we are all entitled to our own opinions as long as you dont go bigger than 15"!
Once I've finished a project why do I start another?

I think one or two people are getting a little carried away with the notion that 17 inch wheels are a sure recipe for death and carnage unless you
drive to Asda on tickover. Both the Elise 111R and the VX220 Turbo run 17 inch wheels on 45 series tyres and whilst not as light as a BEC they are
fundamentally light and very powerful cars. They also happen to be praised highly for their handling prowess.
I have also used a Williams Clio for the last 8 years for sprints, trackdays and road use on 17's and found it very easy to control on the
limit. It was also a second a lap faster round a sprint at Elvington than it was on the same day on standard 15 inch.
I think everyone should be allowed to make their own choice without others questioning their decision.
But maybe one day I will see the light and buy those CXR's you seem to have had for a while type r1.
