At Oswestry i mounted the shocks on the back of the wishbone, with wishbones in right place, to do this, dill a new hole on back of wishbone move shocktower to the rear of bulkhead, get a 30mm screw to attach shock so this clears the camber link, car felt alot better like this!
To run the wishbones around, dill a new hole for the roll bar, turn the wishbones around, leave shocktower on the back of bulkhead, job done, not sure why you need to play around with blocks or cut bumpers like Chris has done, mines fine, car was much better like this than with wishbones the same way, could throw it a lot harder into the corner and get on power much earlyer too! I am even running mine with the quick klips at the back of wishbone to make it even shorter! Pics below, i have made my own carbon bracket to straighten up the cambe links but thats it!

The reason I have done it my way and not yours is - I don't need to make a new camber link mount, and I don't need to drill new holes on the wishbone (which im not confident I can do evenly - which would spoil the whole point in doing it)

been thinking about the way you have done it chris, and it isnt going to shorten the wheelbase, which is what turning the wishbones around acheives and provides more traction!
not saying your way is wrong by any means Paul

hey paul
i had a little play last night with the wishbone mod i turned the rear arms and hangers around when you do this the wheel base is about the same as standard position it seem to genarate good on power traction i think the only fair test can be done is to try all methods back to back i tried the same mod on the d4 and it seem to create the same effect it would be good if shumacher would bring a option to do this. stu

just re read your post its not just to shorten wheelbase it also to move the weight distribution of the rear of the car which would make a bigger diffrence in my opinion. i also tied the same mod on my corraly rdx phi the arms were kept the same just moved the shocks and on my tc it locked the back end of the car so much so i struggled to get it to rotate on tight high bite tracks. stu

You say there the same lenghth but it should be shorter!
Mine is about 5-7mm shorter depending where spacers are than the standard cat, but we noticed at racing last night, 3 cats with the mod with wishbones around, all had different wheelbase, which is strange! Paul

yeah if you turn just thre arms around it is much shorter if you turn the hangers around and trim the bumper it moves the rear arms further rear ward i sat mine next to a standard cat last night it was pretty much the same certanly not 5-7mm diffrence i think it all depends on how the mod is done. stu

I have to admit, I didn't catch on straight away that Chris was talking in his initial post about turning the blocks round as well - this will keep the wheelbase "similar".
Personally, I have tried is with just the shocks moved - and wishbone drilled, and this made maybe a tiny difference. I then tried it with the wisbhones flipped, and the wheelbase shortened by a chunk. This felt good, but maybe a touch too much. I have since modified some bits to take the wheelbase back 2mm, and this feels good. It is shorter than std, but not as short as it can be. Schumacher are indeed making a small kit of parts to reverse the shocks. I'm not 100% sure what parts are coming in that kit to be honest, but it should be available shortly.

I don't want or need to shorten the wheelbase, I generate a bucket load of forward traction already. Doing the way I have done means the wheelbase is around 1-2mm shorter, no more, than a standard car. But aswell as not needing to drill and risk uneven distance holes, nothing except the bumper is modified and so I can easily put it back - and use parts when the Schumacher kit is ready.

This thread reminds me of touring cars.
You should be ashamed of yourselves

Rear mod now available, info from Schumacher -
 New CAT SX Rear Shock Conversion The new CAT SX optional shock layout modification has been developed by the Schumacher design engineers in conjunction with our Race Team. It has benefits for varying types of tracks, however is especially good on very bumpy ones and those with low traction. The tuning bag comes with all the parts required to reverse the shock position to mount on the rear of the wishbone and reduce the wheelbase by 6mm. This enables greater rear weight bias, a more angled rear driveshaft and a more rearward wing position. All these things give the car more rear traction, however at the expense of high speed steering on most surfaces. The new 4mm thick C/F camber link bracket included in the pack also allows for multiple link length’s due to its alternate hole positions.

It's great to see the team and schumacher going forward with idea's like this and bringing them to the masses.

ive been reading this thread and scratching my head. personally i dont believe there is an issue with where the shocks are on the rear end. myself and matt both made the A final at the tally national to be fair i didnt drive that well in the finals but matt qualified and finished very respectable. and then with oz car was awesome from the word go another solid A final. dont think the car could of been better. within the finals i felt i could push alot harder than mossy and was a touch quicker when together in the finals.
this dosent mean to say the next look rear end is wrong as i havent had a chance to try it out. i personally think the issue with the rear end could be solved by increasing the volume of the shocks. i have metioned this the the big man

Just seen the pics on redrc, so does this mean you swap the blocks/arms round to mount the shocks on the rear?
I take it does as just drilling the arms will keep the same wheel base and it mentions short wheel base in the info
