Sorry for the late reply but had internet problems
Depends on what car you looking at.
I have more then 1 Pro10 car.
If it is the blue car then no.
That isn't a 10R5 but a home build car using 10R5 parts and IRS parts.
There are parts on the net to convert your 10R5 to 235MM and also to use stick or 1S lipo(times 2) in your car.
Full options in the UK sells the widening kit for the front of the car and also sells the conversionkit for using stick or 1S lipos.
The easy way to widen the rear is to use the CRC widening hubs or buy a kit from Nitrosisters in Germany.
I have to look in my parts box to see if i have the front wide brace and a lipo kit wandering arround that i am not using if your interested?.
With in a month i should have pic's up from the new car that is going to be build.
