Semi Slick Tyres Too Small

I've got my hands on some semi slick tyres and I've realised that they are too small! They are 205/45/16. The previous tyres were 205/55/16. They look very small on the skyline!! :(

I'd have to adjust the centre of wheel to guard height because obviously it's a fair bit out with the smaller tyres!

Just wondering - is this going to cause any major issues with handling, speed or dynamics of the car?

dont adjust your ride height. your centre of rim to guard height will be the same no matter the size rim/tyre. think about it

you will have a lower top speed, but will accelerate faster.

you will also have less sidewall flex because of the smaller sidewall.

can possibly make the car more twitchy too

Yep you're right, thinking about it now!

Thanks for your input guys!

If anyone's got some 205/55 R16 Semi's lying about that they want to get rid of, let me know :)

Yeah they felt incredibly quick with acceleration.

That could also have had something to do with the fact that my road wheels and tyres are 24kg per corner... The semi's and their rims are only 10kg per corner! lol

I will have to change gears at lower speeds which worries me a bit more though

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
