SPRITE / MIDGET INFO
Due to the amount of information and the fact this site has nearly used all it's allocated web space we have completed the Second Edition of the eBook "Modifying Sprites and Midgets" it's available from Amazon. It contains all the info from the website and much more. It can be read on Kindles or any PC, Mac, ipad, iphone, or Andriod phone with Kindle for PC (a free download). We will try and add more here but it will be a case of moving somestuff off and making some images smaller. UK, USA or put B009HWDDCE or Modifying Sprites and Midgets 2nd Edition into your Amazon search.
If you want to know all about tyres/tires and what the markings on them mean download our book "Tyre/Tire Markings, What do they Mean" also available form amazon UK, USA etc. only 77p , $1 or 0,89Euros. There ends the ads
A little about us. Sorry we don't sell anything we are here purely as an information source, if there anything you would like to share let us know (firstname.lastname@example.org) and we will try to include it in this site. We've been messing with cars and bikes and their engines since the 60's and Sprites, Midgets and A40's since the the 70's, not actually owning one until the begining of the 80's. We've hill climbed, sprinted and autotested A40s, Sprites and others, been involved with customising and helped with race and kits cars. Designing new bits or just modifing existing ones and we've crewed on rallies and for circuit racers. Most memorable being the first race one season where between practice and the race we got one guys engine and gearbox out and got someone to bring another gearbox and fitted that. Whilst we striped down someone elses engine to reseal all the oil way plugs that hadn't sealed. And the last was just a straight forward engine out change the clutch and put it back together. They all made the start, we still try to get along to the Birkett 6 hr each year and support a Sprite team.

Having been a regular visitor to Midget Sprite club sales and wants ads I've notice loads of owners looking for unleaded heads, I do reply if I have time to say I've used Carbonflo since 1982 in all my A-Series cars, none of these have been driven gently most have been hammered around Castle Combe and all (including the A40's) have been happy driving up and down the motorway at the speed limit, I wouldn't speed. I have no connections with Carbonflo and am putting this here because I read it doesn't work. I must be very lucky I've had so many cars (see Nik's Cars) including one with a silly high Comp Ratio but even it came to no harm.
I also notice loads offering Disc conversions that will fit frogeyes and Morris Minors, if they fit a sprite they will fit A30 - 40's, Frogeyes (but check the Kingpins there are 2 different sizes, when you're checking measure both ends as one will be the same and one maybe different) but not Morris Minors you'd need Marina or Ital bits.
