Modding The Rear On My 65..

[G-force]

Don't mean to contradict any advice already given, but logged in here to say the swingaxle cars actually go through corners juat as well as the semi-trailing setup. in my opinion

So if you're on a tight budget, my advice is keep your swingaxles & just fit a z-bar/camber compensator on the rear axle, along with some gas or koni shocks on the rear end. You could also lower the rear about an inch.
You should be able to pull around 0.9G in corners with this setup, even on the stock 155R15 tyres

Only advantage to the semi-trailing rear end is that it holds a straight line better and is generally more predictable.
