Having major issues re-integrating on this site. Cannot seem to get my computer to access and finish uploading from photobucket.

Anyway, if you have a look on youtube for user name LS1280zx and search for hillclimb crash, you will see the demise of my old car.

 

New car started as a spare parts car, bought for $300 for its r200 diff and power steering rack. As it turned out, this car had some serious rust (which has all been cut out and repaired) but not in crucial areas.

Since you are never meant to test your rollcage - and I did, I decided to overengineer a lot of the car. Both front and rear strut towers were strengthen with 3mm plate and the rollcage now extends to towers. Extra bars, extra triangles, got rid of tartga tops and welded up.

Taught myself to fibreglass, made my own moulds, created my own car. So whole front end including doors are now fibreglass, bonnet and doors have extra layer of Kevlar to prevent shatter in case of accident.

Overall weight is now 1200kg wet. Still a bit of a fat pig.

Car runs 295/30R18 tyres all round, still has LS1, although with some trick 5.3 litre heads with 6.0 litre valves installed. About 550hp at motor.

Car took forever to rebuild, now slowly getting back into racing it. Really need some setup work now.

Further updates...

now independent 9 inch 

and Quaife sequential.

 

and I went racing. 

In Australia we call this sport sedans. You can race anything, as long as 6 litre capacity and engine in mid to front. 

Most guys in this video are tube chassis running SB2 chev.

Car is still around. Still drysumped LS2, jenvey throttles with quaife 6 speed sequential and independent 9 inch. 18 x 11 wheels and 300 mm slicks all round, big AP brakes.

Cool car, but the process over 9 years has been expensive. 
3 x R200s, 3 t56 gearbox’s, 3 sets of coil overs, 2 sets of brakes (plus numerous rotors and pads -last set of maintenance rotors and pads was $3400. I motor blown due to oil pressure, one due to a lifter, one cooked, but still ran.

Driveline is not bullet proof, but works hard so requires a little maintenance.

Video is what I class as a diagnostic video. It also happens to show a Z doing a 2.18 lap around Bathurst.


My quaife had dropped one tooth on 3rd gear.

So I had a driver controlled braking issue. I didn’t stop in time. 
mechanically fine, my fibreglass is amazingly strong but needs repair.
The car sat at about 110mm off the ground, without rubbing guards. I have now dropped it another 25mm and guards were engaging tyres. Rather than repeat some bodywork issues I decided to create a little more space.

Category rules are must have front bumber but can extend 100mm forward for undertray and 100mm wider on guards. 
Gonna try my luck making a full front clip. Very time consuming, but oddly satisfying. Fellow competitors pay upwards of $10k for a front clip (mold and one panel set).
Mine will be stronger with lots of Kevlar and prob $2k with replacement panels at half that price. Aiming for less than 25kg for whole front (guards, bonnet and front spoiler). 3C525DC6-CDB7-44A9-B493-E351A1BFABF1.jpeg.39836fd90ec329708bffd59b5e81ab25.jpeg83E548C0-39BF-4ED2-BE88-52D0DF53D5CD.jpeg.ca886ab39c7b52d9baf87f3b977b85dc.jpeg
