I used this from the other forum for getting the angle correct, mine from the wheel to the front of the bumper is 32" unlike his 25".

Basically, measure the height from the front bumper to the ground then the distance from the wheel to the front of the bumper. Mine is 25" from wheel to front, and height was 5-5.5", used 5" for safety. So, with these figures you know the angle (for ramps) which is 10.7 degrees. But you know the front must travel at least 25", before hitting anything over 5". Each step is 13" long, and the height is 1.75".

Based on 1.75" per step, I know 2 steps =3.5", but 3 would be 5.25". So based on the height from my bumper to the ground of 5", I know that the 3rd step must be over 25" away from the 1st.

In theory top one could be shorter and if the height was 5.5" then i could climb 3 steps every 25", instead of 2. And the step could be 12.5" instead of 13". Therefore the ramps overall can be shorter. But I just played safe (ground wasn’t exactly even at measurement).

Conclude for shorter ramps: stopper = 1.5" long, top step = 14", next step = 26.5", next step = 39". Next step (could be final step if only require just over 7" in height, I found this sufficient) 51.5", if not next step is 64". Each platform has 12.5".

And the shopping list:

I bought 3 lengths of 47mm x 250mm x 4.8mtrs of sawn wood from Covers.

1st length 2 x 1380mm and 2 x 920mm

2nd length 2 x 2300mm

3rd length 2 x 1840mm and 2 x 460mm

They will cut all this for you.

That'll give you the 10 lengths you need to make the 2 ramps.

And a box of 10 x 75mm screws.

This is all assuming you have at least 5" clearance from your front spoiler to the ground. If less you'll have to re-calculate.

Hope this helps. icon_thumright.gif

and if you want to take it one step further you could extend the length so you could get the whole car on there and have a stand under each wheel and remove the centre bits, closest you will get to a hoist with out spending lots of cash!

      Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA

      All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.

      roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.
