what fitment and size of wheels do i need?
Evening all,
Am in process of sorting myself out with some wheels. I like the look of the TD Pro 1.2's or the Compomotive CXR1361 or CXR1380.
I am going to go for 13" wheels but wondered what fitment I need? I am running Wilwood Powerlites all round.
Also, should I get slightly wider ones for the back or stick to the same size all the way round? And what size should I be looking at anyway to make
sure they fit under the arches?
Thanks all,
mads

hi mads. what sort of power are you thinking of running? as this may determine tyre width. also id reccomend NOT to over tyre the car. id start by
looking at most caterhams, they seem to run 175-185 fronts on a 6"rim and 195-215 rear on an 8" rim i think. my 13" r500 wheels are
6" fronts 8" rears.
id say for the majority of installs a 185/60/13 front 205/60/13 rear would be a good place to start

Hi Daniel,
In terms of power I am using a 07 R1 with a 3.38 LSD diff so will have stock power of 180bhp at fly.

As Daniel says 185 60 13 fronts and 205 60 13 rear would be a good set up, 6" fronts in the CXR's and 7" rears, but I don't
think pro race do 6" wide 13", so you may have to go 7" all round, you require ET 35 on the Indy R with a 7" rim in a standard
arch

Ive not fitted 6" wide rims on any of my Indys, but its not so much of a problem on the fronts, as you can just adjust your wing brackets to
suit, its just that the wheels have got to look right, ie the dish on the wheel rim's front and rear, with the standard rear arch on the Indy
and a 7" rim 35 et is about as much as you can go on the back, so for the wheels to look right you would have to go for a 6" ET 22 on the
front. But MK now supply extra wide rear arches as fitted to there race cars, thats the route I would go if I was building another Indy, then you can
fit a 7" or even a 8" wide rim with a nice deep dish, the look so much better, as the CXR in ET 35 look very flat, there's not alot
of a dish to them, but the pro race ones on the other hand, due to there design, look ok in a 7" ET 35
It might be a good idea to ring Danny at MK, they supply both CXR's and Pro race 1's, and will be able to advise you on options and sizes
available

IMHO 7" rims front and back is not suitable for a light car
I run 205/55/13 on 7" all four of them, and in the wet, the car is virtually undriveable
I am planning on reducing to 6" rims with 185/55/13, at least on the front
plus my car is a Car engined car, and still light, but not as light as a BEC
Just my opinion
