    Astra sprot hatch BTCC - engine options?

    Ooops Sport Hatch!!!! So I went a bit mental and bought this a few months ago. Plan is to use it for trackdays for the next year or 2 then race it in the historic touring car series. Swindon have quoted £15k to refresh the original 2.0 NA Sodemo engine – (L850 architecure same as Z22SE) and...

    AD08R vs DZ03G vs Pilot sport 3 @ moist Silverstone GP

    My bro and I had a track day @ Silverstone last Tuesday, we run nr. Identical Astra-G’s Z22se with similar chassis mods - were a competitive family!!! I have 2 sets of tyres, Michelin PS3 on standard rims & Dunlop DZ03G Semi-slicks on Supertourings. My bro has only Yokohama AD08R on standard...

    Scrub Radius vs Offset

    Moving Battery to Boot Astra-G

    Drove my wifes 1.6 SXi on std suspension the other day, the front end feels nicely balanced, ultimately not as much grip as mine on B12's but just a more 'pure' feel. Guess this is due to the lower weight on the front axle. So for my daily driving mild track day car I'm thinking of moving the...

    Astra-G Bilstien B12's fitted

    Well I've never been one for modding I've always preferred a standard car with the belief that if you want something better then go buy the complete car. So a mate who works for Mazda offers me a free track day @ Donnington last week so I decided to take the plunge and fit some upgraded...
