In 1990 the club became affiliated with the Australian National Street Machine Association which enabled members to have their HDT or HSV vehicles, either standard or modified, insured at significantly lower rates than available in the market to non-members. This more affordable insurance for cars that were prime theft targets set the stage for a period of good membership growth over subsequent years.

A new 7 page constitution was adopted at the start of 1990 for the “HDT Owners Club of NSW” and published in the September edition of the Club’s magazine.

The Club finished 1990 with $11,914.10 in the bank.

A test race open to Superbikes was held in July 1990 and Eastern Creek Raceway was officially opened by then New South Wales Minister for Sport Bob Rowland-Smith on 10 November 1990 with the running of the Nissan Sydney 500 endurance race for Group A touring cars. In 1991, the consortium formed to fund the circuit suffered financial problems and the complex was purchased by the New South Wales Government.

The Club 10 cars were due to display at All Holden Day at Butterfly Farm, Wilberforce where a total of around 400 cars were expected. The event scheduled for 5th August had to be postponed to 2nd September due to flooding. Unfortunately this date clashed with the weekend Away to Altamira Holiday Ranch, Gloucester so not all originally entered vehicles could display.

Club Member Lui Rapisarda was killed while competing at Queensland’s Willowbank Raceway. Lui died when his Top Fuel dragster suffered a mechanical explosion laid oil onto the rear tyres ans sent him skidding into the armco. Lui and his father Santo raced under the banner of Rapisarda Racing and was the latest member of the “Five Second” Club having run a 5.7 hot seconds pass at Calder earlier in the year.

1990 Club Magazines:
The 1990 Club Magazines started with the May edition in a stapled A4 Newsletter format as below. With the July 1990 edition, new Magazine Editor Robert Heard introduced a glossy full colour cover and printed pages (courtesy of Darrin Renouf of Peachy Print) to replace the photocopied Newsletter. He also changed to the current bi-monthly publication. For economic reasons, the cover was printed in bulk and then used for the September and November 1990 editions as well.
