meh
you would think that it makes sense to have the same width on both front and rear end so that you dont get a shitload of traction at the rear and none at the front which could cause belts to bend??

im probly wrong but i was taking a stab into the dark

Its the same as running diff compounds, except if u run 30mm, u could also run slightly harder compound/insert and save on how many tyres u have to spend

lol its fine, im 100% positive but i believe that that is the reason.

mainly to get more grip with out moving out of the heat range of the tyre.



Edit: NOT 100% positive

Im not normally this forward but........BULLSHIT!!!!!!

I have owned over 6 rotaries, turboed, Electronically injected,
j-ports, peripheral ports, bridge ports and heres the thing never have i seen a rotary put out 450kw. Possibly a Japanese works engine but I would have to see the dyno sheet to believe it!

By the way, last night I rang 3 of the great rotary gurus in oz. Ric Shaw, Bill (aka Pacman) and Phil Alexander and I swear they havent stopped laughing yet at that figure.

On a lighter note, good on ya and have fun with the car, by the way what model is it?

Not quite, by running harder tyres on the front you eliminate a lot of oversteer and compensate by learning to back off on the throttle.

The RX4 has around 220KW at the moment, it still has to be J-ported, turboed, and all, but just for the j-port it will lift to 300KW.

The Rx 7 i will get soon hopefully will be worked to the absolute shit house and estimation for its power is between 350-450 depending on EMS being ran and the Turbo that gets hooked.
Plus mircotech have turbos for rotarys that get up to around that sorta power. 1750 for just the turbines.

the RX7 will b a 1980,

The RX4 IS a 1974 model.
and its about to have a motor change to a 1991 13b Twin Turbo out of a RX7 series 2.


Note: 450KW was an estimate. not actually built the engine yet.
b about another year or 2 b4 the engine even starts to get worked.

Glad we clarified that Rotaries just happen to be an ex-obsession I once had. I still have ceramic apex seals, assemby jigs and shit around here.

A phone call easily answered that, the figure quoted is an estimate only and is based on a 20b engine and Archie stated the following;
1) There is no Dyno figure on this engine
2) The cost to date in excess of $50'000 (thier cost)

Therefore you will need to grow an extra rotor!
and fork out around 60grand+ engineering costs

How long do a set of foams last if you race fairly conservatively?

no its becasue i run 40s on the front and 37s on the rear and 26mm fronts and 30 mm rears, the reason for this is the rear tyers are softer so i can get rear grip but in getting that with a softer compund the tyers will wear out quicker but if u have more of the tyers on the road less will get eaten up

and the main reason is just to get more tyer on the road
